Best Double Cranksets for Mountain Bikes

Thursday July 13thBike Parts Category

Things to bear in mind when buying a MTB Double Crankset

You don’t always get what you pay for: While the top-end carbon-based cranksets are undoubtedly things of beauty, they’re not much lighter than top-end aluminum-based cranksets.

 

Ditching a chainring doesn’t mean losing one-third of your gears: The conventional triple chainring setup leads to overlapping of gears, so a 3×10 drivetrain may only yield 18 or so unique ratios. This overlap is reduced on a double, and trouble-free chain lines mean there are no sprocket combos you can’t use.

 

Switching to a double won’t save much weight: You might not be saving more than 50g by doing without a granny ring, so don’t choose a double on weight grounds.

 

Be careful with your gear ratios if you’re not super-fit: Some bigger ringed doubles can leave you running out of gears on steep climbs; go for 26 teeth or fewer if you have fitness doubts.

 

Cranks that look good on the shop floor don’t always stay that way on the trail: While we like the look of black MTB double cranksets, the silver or polished outer crank surface options stay looking good for more rides.

 

Anatomy of a Crankset

 

Chainrings

 

Almost all manufacturers use shaped teeth, ramps and pins on the inner edge of chainrings to help guide the chain between the rings. Some are more efficient than others, but front gear mech positioning and adjustment is equally important. Only having two rings cuts down on chain line problems and, if twinned with a shorter axle, results in a shorter distance between your feet (Q factor), said to be more efficient for pedaling.

 

Axles

 

Different cranks use different spline setups on the axle. Some slide onto the spline and are fastened tight by a bolt threaded into the end of the axle. Others involve the crank being pinch tightened around them. In both cases, spacers dictate ideal positioning for chain line, crank clearance and a snug fit with smooth-running bearings and no play.

 

Bottom Bracket

 

Square-taper bottom bracket axles with cups and bearings inside the frame shell are still available but most new cranksets now have an oversized hollow axle fixed to one crank, a splined axle onto which the other crank is bolted and bearings that fit into cups outside the frame’s BB shell.

 

We’re not testing BB30 or other oversized cups/axles in this test, but it’s worth being aware that they’re creeping in at the top end of the market as a way of trimming weight and boosting drive stiffness on top end frames. A BB30 bottom bracket has bearing cups that press-fit into the frame.

 

Bash Guards

 

If your rides involve log hops and/or rocky step riding, you’ll probably already know that slamming the big ring on logs/rocks will damage the teeth. Double cranksets have smaller outer rings, reducing this problem, or you could get a crankset with a bashguard instead of the big chainring.

 

Stiffness and Weight

 

Extra weight can add stiffness to cranks just as less weight can add flexibility. The skill of making great cranks at any price is to create stiffness where it’s useful while trimming weight where it’s not. Just don’t expect very light and very stiff. There’s usually a trade-off.

Tips to Select a Touring Bike for Your Cycling Vacation

Thursday June 29thBike Parts Category

There are a number of bikes that are available in the market from mountain bikes, traditional folding bicycles to road bikes. Each type of bike is designed to apprehend and serves different interests to travelers. Every year, many people plan a cycling vacation to some of the most beautiful places of the world. If you’re planning a cycling vacation, it’s likely you will need a strong and sturdy bike. Your bike should be capable enough to carry heavy objects so that you can bring essential supplies along with yourself.

 

Before you start your cycling expedition to Europe or anywhere around the world, make sure you have the proper bike and touring equipment. A touring bike is necessary to ensure that your riding experience is favorable. Below is the general list of the main attributes to select a touring bike:

 

  1. Strong and Sturdy Frame: The frame along with the fork is the most important part of the bike. You must select a bike that has a strong and stiff touring bike frame and body. Strong frame helps to stand up the tortional stress in curvy paths, while weaker frame starts to bend and flex. It is the heart of your bicycle. So, buying a bike with a rigid and tuff frame is very essential.

 

  1. Long Chain Stays: This is the most desirable feature in your touring bike. A long chain stays makes your wheel base longer and much more stable. It also solves the problem of heel strike on your rear pannier as it provides better stability to your feet. It also provides your frame more clearance, by allowing more space between the wheel and the seat tube.

 

  1. Uncut Steerer Tube: This is another desirable feature while selecting a touring bike. An uncut steerer tube provides more flexibility to your handlebars to move up and down. Most people like the handlebars in level with the saddle, and a cut steerer tube makes it difficult to achieve. If your steerer tube is cut already, then this will restrict your bike moves.

 

  1. Relaxed Geometry: Your bike’s geometry mainly depends upon the bike frames, as keeping frame angles more relaxed. A relaxed geometry promotes a more comfortable, relaxed style of riding. It means keeping your angles within your frame tube. Therefore, select a bike to be ridden in a straight line.

 

  1. Large Tires: Tire size is another significant feature while selecting a touring bike. If you are touring on rougher roads or tracks, bigger tires can grant you better protection. Bigger tire provides more air and ultimately better suspension.

 

  1. Water Bottle Cages: A good touring bikes have at least three bottle cages, on the top of the downtube, front of the seat tube and the underside of the downtube. This can be very useful for carrying extra water on long tours. You can even get your bike custom made for carrying some extra loads of water and fuel for cooking.

 

  1. Good Load Handling: Your bike should be capable of carrying enough loads while travelling. Do not buy a touring bike without trying it out in fully loaded form. Take a little ride around the bike shop’s parking lot. This will give you an idea, that weather your bike have the capability to handle the load on tour.

 

Some destinations have easy terrain while others may have high jagged peaks. You must select a touring bike on the basis of destination you are going to visit.

 

Spend time researching different bike types, accessorizes and feature required in your bicycle. If you are not clear which bike will suit your requirements, then you can ask your tour operators to provide you a bike as per your needs and requirement.

Buyers Guide to MTB Bike Stems

Tuesday May 23rdBike Parts Category

What length is best? Is it possible to go too short? Are long stems good for anything at all? All the answers are here.

 

Length is everything

 

A MTB bike stem’s stated length is not simply the length of the whole stem front-to-back. Stem length is measured from the middle of the headset stem cap bolt to the middle of the handlebar. Got it? Good. See the pic below for how to measure (it’s a 70mm stem).

 

Stem length affects how all bikes ride but stem length is extremely significant when mountain biking. It is one of, if not THE most important aspects that governs how a bike handles.

 

A bike without enough reach can be uncomfortably cramped and prone to wandery climbing. Your bike’s top tube length is going to dictate just how short you can go before you start to encounter too many negative handling traits.

 

If you have a bike with a short top tube then putting a short stem on it will probably not result in good handling. It will be like riding a bike that’s too small for you. You will find it hard to ‘work’ the terrain and you’ll be generally unbalanced from being so upright.

 

On most modern mountain bikes you should be aiming for a stem length somewhere between 50mm and 80mm.

 

A quick note about handlebar width

 

Handlebars work in conjunction with stems to dictate where your hands end up and thus your overall front end weighting and positioning.

 

Some riders switching to a significantly shorter stem will benefit from also increasing their handlebar width. It’s a bit hard to explain why here but basically it keeps a bit of the overall reach that they’re used to but adds stability and control.

 

Rise

 

Stems come in different amount of rise ie. the angle of the stem’s body. Because stems have got shorter over the years, rise doesn’t actually make that much of a difference to bar height any more. There’s only so far up or down a stem can go when it’s short in length.

 

With mountain biking your front end height is now much more dictated by your handlebars. If you want a higher front end, you need bars with more rise to them. If you want a lower front end, you should try some flat bars.

 

If in doubt the best place to start is a stem of around 5-6 degrees. Or a zero degree stem if you’re considering a stem shorter than 70mm. This gives a nice neutral placing of the bar clamp area without committing you to an overly tall or low front end.

 

Bar diameter

 

Bar clamp diameter is the diameter of the handlebar where the stem clamps on to it ie. the middle.

 

If your mountain bike is even remotely new it will have a handlebar clamp diameter of 31.8mm. The previous standard diameter size was 25.4mm. If you’re unsure just grab hold of a tape measure or a ruler and have a quick look. It’ll be obvious which of these diameters it is.

 

Because this is the mountain biking industry and we love introducing new ‘standards’ every five minutes there is now another new clamp diameter standard on the market: 35mm.

 

If you want to add even more stiffness up front then consider making the move to 35mm. Bear in mind that you’ll need a new handlebar as well as a stem and they’re currently aren’t that may companies supporting the 35mm size just yet.

 

Construction

 

Virtually all stems are made from aluminum. Steel is reserved for super cheap bikes and kids bikes. Titanium used to be in vogue in the 90s but these days carbon fiber is the material of choice for those with more money (than sense).

 

CNC machined aluminum stems cost more than forged and welded stems but they often stiffer. Some people also just like the look of CNC’d stuff.

 

Clamp design

 

There are two clamps on a stem. A handlebar clamp at the front and a fork steerer clamp at the back.

 

Almost all decent stems use a 4-bolt design for the front bar clamp. Strong, stiff and less creak-prone than old fashioned 2-bolt face plate designs.

 

The rear clamp – where the stem fits on to the fork steerer – sees a tiny bit more variation in design. The vast majority use a 2-bolt design. Some DH stems use a big single bolt at the back. Some longer XC stems use a wedge design with the bolt situated in the body of the stem in front of the fork steerer.

 

It’s a good idea to look out for a stem that doesn’t have rear clamp bolt heads that protrude too far out. These can really hurt your knees if you crash. Most decent stem designs have cowled or rounded-off bolt head designs.

 

Which MTB bike stem should you buy?

 

Leisure riders – Don’t worry too much about weight and clamp design. Get a 80mm or shorter stem that fits your handlebar and that’s it. As usual, check the sale sections for bargains.

 

Regular riders should try as short a stem as their bike frame’s top tube allows before it gets too cramped. There are not many riders who’ve regretted slapping on 60-70mm stem and enjoying the immediate handling benefits.

 

Racers will want to avoid heavy stems but the key quality they should look for in a stem is stiffness. CNC stems should be on your shortlist. Spendy racers may wish to consider carbon. There’s also the new 35mm standard if you don’t mind buying a new handlebar as well.

What Is a Bike Headset?

Thursday March 23rdBike Parts Category

The headset of a bicycle is, in simplest terms, the part of the bike that allows the steering column and front wheel to rotate and turn. It is, therefore, fairly important to the general running of a bike (as we’re sure you’ll agree!)

 

A bike headset generally consists of two cups that are pressed to the top and bottom of the headtube, there are bearings inside the cups that provide low friction contact between the cup and the steerer. This setup allows the rider to be able to steer and operate the bike with maximum efficiency.

 

Today’s bikes use lots of different headset styles, so we’ll take you through a few of the most common ones (because we’re nice like that).

 

  1. Threaded Headsets :

These headsets are the most simple and ‘classic’ of all headsets. They were once nearly ubiquitous, but times have moved on since then, the “threaded” in the name refers to the external threading at the top of the fork steering column. Bearing cups are pressed into the bike head tube. The bearings, which may be loose ball bearings, retainer ball bearings, or cartridge bearings, sit above and below the pressed races. The top most bearing-race has internal threading, and is held in place by a threaded locknut. The stem has no effect on the headset adjustment.

 

  1. Threadless Headsets :

Threadless headsets are actually quite similar to their threaded cousins, with one major difference (and you’ll probably see this one coming), there is no threading, The top race uses an internal centering sleeve on the column to maintain alignment to the bearing cup. Pressure is applied to the top race from the stem. Threadless Headsets must use a compatible stem that matches the steering column diameter. The stem binds to the outside of the column, and holds the top race in adjustment. The threadless standards are 1-inch and 1-1/8 inch diameter steering column.

 

  1. Low Profile Headsets :

Alternately known as ‘Integrated Headsets’, ‘Internal Headsets’ and ‘Zero Stack Headsets’ (amongst others), these headsets use pressure frame cups to secure the bearings, The cups have a flange, or lip, and sit adjacent to the outer edge of the top and bottom of the headtube. The headtube is a relatively large outside diameter, approximately 50mm, and cups allow the bearings to sit flush or even inside the headtube. The headset bearings sit “internally” to the top and bottom of the headtube. Some models use a cup that holds a cartridge bearing. The cartridge bearing is a slip fit into the cups. The cups act as a bearing holder and do not take bearing movement or wear directly. Other types have the cartridge bearing and cup/holder as a unit. These are simply replaced as a unit when it is worn out. Still another version of this type uses a cup and cone system with caged ball bearings, similar to the conventional thread less headsets.

 

Of course, it’s up to you to decide which of these styles best suites you and your bike.

Basic Bicycle Parts That a Cyclist Needs to Know

Thursday February 2ndBike Parts Category

Frame

 

The frame is the heart of the bicycle. It is the mechanical core that provides points of attachment for the various components that make up the machine. Most frames are diamond shaped consisting of two triangles: front triangle and rear triangle. The front triangle is made up of head tube, top tube, down tube and seat tube. Frame is the most important of all the bicycle parts. The rear triangle consists of the seat tube and paired chain stays and seat stays.

 

Drive-train and Gear

 

Drive-train and gears are the bicycle parts that make the machine moves. Obviously without these two, bicycles will never be called a mode of transportation. The drive-train is an indispensable component of a bicycle it is connected with the pedals which rotate the cranks, which are in turn held in axis by the bottom bracket. The drive chain then transmits the power to the rear wheel and then propels the bicycle forward.

 

Gears in various gear ratios are the bicycle parts that help cyclists maintain an optimum pedaling speed while covering varied terrain. Different gears and ranges of gears are appropriate for different people and styles of cycling. Multi-speed bicycles allow gear selection to suit the circumstances: a cyclist could use a high gear when cycling downhill, a medium gear when cycling on a flat road, and a low gear when cycling uphill.

 

Handlebars and Saddle

 

Handle bars and saddles are the bicycle parts that give the rider control and ease when riding the bicycle. Handle bars are mainly used for steering and control the direction of the bicycle. It is also in the handlebars where the accessory and brake controls are mouthed. The saddle which is the part where the rider sits on is place on the seat post near the rear end of the bicycle. The seat post is placed in between the two wheels to maintain balance and easy control.

 

Brakes

 

Brakes are the most important bicycle part when it comes to safety. As per standard all bicycles are made with two brakes, one in the front wheel and the other in the rear wheel. There are different types of brakes each having its own purpose. Rim brakes and disc brakes are operated by brake levers, which are mounted on the handlebars are commonly used in off road bicycling. Coaster brakes are operated by pedaling backward are mainly used in on road biking.

 

Wheels and Tires

 

A bicycle is called a bicycle because of its two wheels. The two wheels of the bicycle are commonly referred to as the wheel set. Modern bicycle wheels are traditionally spoked. Tires vary enormously, they can either be thin, called skinny, for road biking, or may be thick such as used in off road biking.

 

These five are the basic bicycle parts, other devices that are attached to the bicycle are referred as the accessories such as head and tail lights and water bottle. Without the above mentioned the bicycle cannot function.

How Important Are MTB Bicycle Frames?

Friday November 25thBike Parts Category

MTB bicycle frame is the basis for the bicycle’s sturdiness, weight and general appearance. This is why when purchasing new mountain bikes, most cycling professionals and enthusiasts give the frames a thorough check instead of just giving it a casual or cursory look. Though it may appear similar to a casual observer, each frame has different sizes, symmetry and materials used which is tailored for a particular body structure of the cyclist who will be riding it.

 

Most of the mountain bike frames available in the market today is usually made up of aluminum steel. This makes for a sturdy, yet very light structure, making it easy for the cycling enthusiast to maneuver. Although there are still frames that are made up of galvanized iron or steel, these are rapidly fading fast into oblivion and is being replaced by aluminum and some other lighter materials like titanium.

 

Naturally, if you are a cyclist, you always undoubtedly would prefer the lightest material to make up your frame. This is where the ultra-lightweight metal call titanium comes in. Bike frames that are made of titanium are almost weightless, yet are sturdy enough to withstand the rigors of cross country cycling. The only problem with titanium as of the moment is the exceedingly high cost which only a few cycling enthusiasts can afford. This is why most cycling enthusiasts still prefer their bikes to have aluminum frames because they are very affordable. Though they may not be as light as those frames which are made from titanium, aluminum frames do exceedingly well in various types of tracks.

 

Another area of consideration which you must carefully check out is the size of the frame. Bear in mind that MTB bicycle frames have different sizes which correspond to the height and body physique of the cyclist who would be riding it. The size of the mountain bike frame is usually determined by measuring the expanse of the frame from the center of the base bracket to the uppermost portion of its top tube.

 

Getting the right bike frame is very important since it can affect the way you maneuver your bicycle. Remember that all frame sizes are influenced by the unique body structure of the cyclist who will be riding it which is why you have to carefully select the MTB bicycle frame with a size that closely matches your own body physique.

 

Once you have correctly determined the weight and the size of the mountain bike frame that you consider perfect for your body structure, you can now begin that exciting cross country journey that you have been longing to indulge into. If you need further information about MTB bicycle frame, welcome to visit the website of MAXWAY and feel free to contact us!

How to Choose the Right Bicycle Saddles for Riders

Wednesday November 16thBike Parts Category

Finding the right bicycle saddle is crucial since this greatly affects the rider’s comfort and performance in their ride. Picking the right saddle is actually challenging for all riders regardless of their weight and size. For heavy riders however, the additional weight and pressure put on the seat may cause discomfort and strain. Here are a few things heavy riders may want to consider in choosing a saddle for cycling comfort.

 

Consider the width of the saddle. The idea of the saddle is to support the two “sit bones” to keep the rider balanced on the bike. Heavy riders may want to consider choosing a slightly wider saddle for better support and comfort on their backside but not too wide as this may cause chaffing or rubbing.

 

Consider the bicycle saddle pad. It is a misconception that the best saddle pads are those that are soft and thick. While these types of pads can be comfortable in the beginning, these can cause excessive heat as these absorb much pressure from the rider’s weight and movement and thus create discomfort during the ride. Experts suggest that heavy riders get a saddle seat with firmer foam since this doesn’t quickly compact compared to a foam or gel cushion. Also, experienced heavy riders agree that it is wise to choose bicycle saddles with the least cushioning but still is comfortable for the rider to sit on. It may take some time to get used to riding a firm saddle but over time, the ride would be more pleasant.

 

Consider durability. Because foam saddles easily wear out for heavy riders, these have to be replaced more often than a lighter cyclist would. Experts suggest that leather saddles can be a great option for heavy riders since these are more durable. Also, the longer the rider stays on the saddle; the seat becomes molded to the rider’s anatomy.

 

Shop wisely. It is advisable that a rider give the bike a test ride before buying it. During the test ride, the rider may vary positions on the saddle, ride on different speeds, hit some bumps and try some uphill terrain. This way, the rider can test the comfort of the saddle seat and the sturdiness of the saddle seat. Also, it is suggested that the rider also inspect the rails of the saddle. Although chromoly is the most affordable and suitable for most riders, titanium rails are more durable and long-lasting.

 

Considering all the factors, the key to finding the right bicycle saddles is optimum support and comfort for the rider.

We are proud to offer the finest quality bicycle saddles, frames, forks, handle bars, bar ends and much more to customers and OEM producers around the world.

Guide to Track Bicycle Frames

Monday September 12thBike Parts Category

For those who are very much in love with the outdoors and has a thing for adventures, having a track bicycle is something that could be deemed a dream come true. That is because having a track bicycle would enable the owner to engage in all terrain and other outdoor track sporting activities. So, just what is a track bike, really? From what has been portrayed a while ago, a track bicycle is basically a bicycle that is especially designed for use in the race track and the outdoors.

 

The Frame of a Track Bike

 

The track bicycle frame basically refers to the sort of skeletal makeup of the track bike. It is also known by the term of track frame. So, why is it important to be able to know the specifications of a track frame? For those who are considering purchasing a track bike, it is essential to be able to know just what a track frame exactly is so that they will be sure that they are making a wise buy.

 

So, now the question is what are the specifications of a track frame? To answer this, we need to know just what a track bike really is. A track bike is basically one of those bicycle models that have fixed gears. Thus, when we speak about the frame of a track bicycle, we can say that it has just one gear without brakes. It also does not have a free wheel.

 

Speaking about the tires, it is important for a track bicycle frame to have tires that are inflated at a high pressure so that the level of rolling resistance would be considerably lessened. It is also vital that the tires are narrow for it to be able to maneuver into dirt roads more effectively and efficiently. While tubular type tires are still available and still all right for use on a track frame, clincher tires are now the more preferred kind of tires because of the more durable construction.

 

Meanwhile, as per the specifications set by the International Cycling Union, which is main governing organization when it comes to bicycles, a track bicycle frame should always be distinguished by the following qualities:

 

  1. Minimal fork rake compared to other types of bicycle frames
  2. A head tube set higher so that steering will be more stimulus sensitive
  3. A bottom bracket that is set higher, which is needed for the pedals to avoid getting in contact with tracks that are banked steeply
  4. A seat tube that is installed at a kind of sharp angle for powerful aerodynamics
  5. A rear hub that employs a spacing of about 120 millimeters
  6. Track ends, otherwise known as dropouts, facing the rear so that the adjustment of tension in the bike chains is easily facilitated.
  7. Clearances that are built very tightly together at the front of the tire at the rear, which is important in preventing the accidental removal of the wheels of the track bicycle.

Types of Bicycle Lights

Wednesday August 10thBike Parts Category

There are many different bicycle lights to choose from, and it can be difficult to choose the best one for your needs. Things to consider include the type of light bulb, the power source, and where you want to mount the light to your bicycle.

 

Bicycle head lights are those mounted to the front of your bicycle that are white and help you to see ahead of you and help others (drivers and pedestrians) see you. Depending on your riding conditions, you might settle for a cheap headlight system that is more to help others to see you to prevent accidents, or you might need a bright light to help you find your way on a dark bicycle path.

 

Depending on the length of time and frequency of your nighttime riding, you might decide on an alkaline battery powered light, or one that you can charge while at work before your evening bicycle commute home. The type of light bulb (LED, and halogen are two common types) can affect how long the battery lasts, and also the price of the system.

 

Rear bicycle lights are always red and are strictly to help others behind you to see you. These lights can be set to blink mode or steady. Blink mode is essential to your safety especially while riding on a road at night. The blinking will help draw attention to you while a steady light might otherwise be overlooked. These lights most commonly use LED bulbs. Some rear bicycle lights can be seen a great distance, while others might not be bright enough to be seen quickly by drivers in conditions where there are many other lights around.

 

Different types of bicycle lights also have different power sources. The simplest and most basic are standard non-rechargeable alkaline batteries. These batteries are cheap, but they are wasteful. However, they tend to last a very long time. Many bicycle lights these days are using lithium-ion batteries. These small compact batteries hold a long charge and can be recharged hundreds of times. Many lithium-ion powered lights can even be charged from the USB ports on your computer giving you a quick and easy way to charge your lights without having to use a dedicated charging adapter.

 

While headlights are typically mounted to your bike’s handlebars, many lights can also be fitted to your helmet. By having the light on your helmet, it enables you to direct the light to exactly where you need it. This can be helpful in intersections since it allows you to direct the light right at a driver to help them notice you. Rear lights are typically mounted to your seat post, but many can also be mounted to your clothing or a backpack.

 

Though there are many different types of bicycle lights to choose from, it is essential that you have lights on when you ride in low light conditions or at night. Your safety depends on it!

Tube Bender Machine – Types and Kinds

Monday July 25thUncategorized Category

Tube or pipe bender is essential in a lot of industries. It can be done with precision and ease with the right machine. While most heavy-duty benders are reserved for bigger industries and machine shops but there are some more affordable and practical that can be used even without much experience.

 

Because of its equilateral composition, a tube can be bent in multiple angles and directions without losing much tensile strength. A tube can be safely bent anywhere up to 180 degrees. Its openings can also be made to fall on different planes-three-dimensional bending.

 

In each kind of machine, the process adheres to a basic principle. A tube is loaded into a bender which is clamped into place between two dies. Mechanical force is used to push the pipe against a die which forces it to conform to the shape of the guide. This is often done by rotating or rolling its end around it (die).

 

The basic principle above is used in the different classes of benders enumerated below. Each bender type is different in the way it applies mechanical force to achieve the bend.

 

Press bender

 

Probably the most basic type of bender is the press bender. As the name suggests, mechanical force creates the bend by pressing the tube against a die. The force is usually applied hydraulically or pneumatically, depending on the configuration of the machine. This type of bender can be used on cold pipes but it usually deforms the cross section at the bend to an oval shape due to the lack of internal support.

 

Rotary draw bender

 

A rotary draw bender is more precise in its bends because it uses a constant center radius. Counter and former dies work together on both sides of the bend, guiding the tube precisely as it travels the length of the bend. This type of bender creates nice bends that have little to no deformation. Because of this, it is a popular choice for the creation of rails, frames, bike and motorcycle handles, and racing car roll cages.

 

Heat-induction (method)

 

While technically not a type of bender, heat-induction is often paired with an external tube bender machine. In heat-induction, heat is induced into the section of the pipe that will be bent. While the pipe is hot, pressure is placed on the pipe via machine. It can also be used on larger pipes that are hard to fit on a bender-petroleum lines, power plants, etc.

 

Roll benders

 

A roll bender is different from the other types as it gradually changes the bend radius in the pipe over several passes to the rollers. The rollers usually work in sets of three, sometimes in a pyramid formation where only the topmost moves and applies the force to move the tube and create the bend.
