10 Bike Fit Components That Solve Real Fit Problems

Introduction

Bike fit problems are rarely solved by a single adjustment. A rider who cannot comfortably reach the brake levers might need narrower bars, a shorter stem or a different lever body. A rider with sore knees might need a wider stance, shorter cranks or a different saddle position. What follows is a roundup of ten components and tools that address specific, recognisable problems rather than promising a general improvement.

Some of these items suit very small riders. Others suit riders with wide feet, riders with hip impingement, or riders who simply want to raise their front end without replacing the bike. A few are workshop tools rather than parts you would fit at home.

What These Components Have in Common

Three themes run through the list. First, ease of adjustment: parts that can be set up quickly and repeatedly, which matters while a position is still being refined. Second, availability in sizes much of the market does not bother to make, whether that means a 32 cm handlebar or a 160 mm crank. Third, a clear relationship between cost and benefit, from a set of pedal washers that costs very little to a professional fitting jig built for fitting studios.

Ergon VCLS Seatpost: Saddle Tilt Made Simple

The Ergon VCLS is a leaf spring carbon seatpost built from two separate components. It is often seen on Canyon bikes, though the post itself is manufactured by Ergon. The suspension design gives the rider a useful amount of vertical compliance, but the reason it stands out is the way the saddle angle is set.

A single bolt at the bottom of the post locks the two pieces together. Loosen the bolt, lift the post out of the frame, set the saddle rail angle, refit the post and tighten the bolt again. For anyone who spends a lot of time adjusting saddle tilt, that sequence is hard to beat, and it is what separates this post from conventional two-bolt designs.

Fourier Handlebar: Narrow Widths Down to 32 cm

Handlebar width is measured centre to centre across the point where the controls are mounted. For most of the market, the smallest commercially available width is 36 cm. Riders who need something narrower have traditionally had very little to choose from.

The Fourier handlebar is available in 32 cm and 34 cm widths. It is imported in small volumes, which means the minimum order quantities involved are significant for a small business, but the bars themselves are inexpensive at around £50. For smaller riders, and for riders who are not especially small but still prefer a narrower bar, that width range is a genuine game changer.

Lake CX-238: A Wide Fitting Shoe as Standard

The Lake CX-238 is a wide fitting shoe as standard, so riders with wide feet usually do not need to order a separate wide version. The white colourway in particular is extremely wide. It uses a leather upper, a double barrel closure and a carbon fibre sole.

Because the fit is so generous, feet should be measured and assessed before buying. Even the extra wide versions of Lake’s higher end models are not wider than this shoe. There is also a mountain bike and gravel version that uses the same last and the same upper, with a two bolt sole instead. That means a rider can keep an identical fit across a road shoe and an off-road shoe rather than reworking their position when they switch bikes.

Riser Drop Handlebars: Specialized Hover Bar and Genetic 25 mm Rise

Riser drop handlebars raise the front end of the bike without changing the frame or the stem. They are a useful option when a rider needs the bars higher, and they avoid the handling compromises that can come with inverting a stem. They can also help with neck, shoulder and hand issues.

Specialized were the first to make this style of bar. The Hover bar was originally designed for the second generation Venge and is now available for more conventional front ends, with a choice of 25 mm and 40 mm rise.

Genetic also makes a riser drop bar with a 25 mm rise, which gives riders a second option in the same category.

Shimano 105 Hydraulic Short-Reach Brake Levers

Shimano developed a lever design intended specifically for small hands. The body is shorter than a standard hydraulic lever, which reduces the reach to the back of the hood. It is only available on the 105 hydraulic groupset, historically in 11 speed form.

If reaching the brake levers from the drops is difficult, the cause is often a bar that is too wide or a reach that is too long. When bar width and reach have already been optimised and the problem remains, a shorter lever body is worth considering.

Short and Ultra-Short Reach Handlebars from Specialized

Reach is measured from the centre of the bar to the point where the controls are mounted. Most of the shortest handlebars on the market come in at around 75 mm. Specialized short reach handlebars reduce that figure to 65 mm, which takes a meaningful amount of length out of the front end.

Specialized also offers an ultra-short reach version, measured at 65 mm as well, giving fitters a second shape to work with when the aim is to bring the controls closer to the rider. This is most useful as a last resort, once the shortest viable stem has already been fitted.

160 mm Crank Arms from Shimano and SRAM

For years, the shortest commercially available crank was 165 mm. That changed when Shimano and SRAM both added 160 mm options. Shorter cranks make it easier to come over the top of the pedal stroke, which matters most for very small riders and for riders with hip impingement. These arms are still not as short as many fitters would like, but the direction of travel is right.

Shimano offers a 160 mm crank in its 105 groupset.

Shimano also offers 160 mm cranks in Ultegra.

On the SRAM side, 160 mm cranks are available in Force.

SRAM also offers 160 mm cranks in Rival.

Since all four options share the same 160 mm length, the practical question is which groupset the bike already runs.

Supporting Details: Stance Width and Video Analysis

Not every useful fit change is a component swap. Two millimetre pedal washers move the feet further apart, which can improve knee alignment and relieve pressure on the outside of the feet. They provide roughly the maximum stance width increase that still keeps good thread engagement with the pedal, they work with almost every pedal system, and they are cheap, fast and easy to fit.

Video analysis supports the same work from another angle. Recording a rider in four planes, left, right, front and rear, treats the rider as a three-dimensional entity instead of assuming that both sides behave the same way. Unlike motion capture, it does not physically measure the rider’s movement; instead it allows a before and after comparison, so a change such as a new saddle can be filmed again and any real difference quantified. Cameras running at 60 frames per second are used for this, considerably faster than the 18 frames per second of the industry-leading motion capture system.

Purely Custom Fitting Jig: Optimising Position Off the Bike

Historically, bike fitting has been carried out on the rider’s own bike. The Purely Custom fitting jig changes that. It is an infinitely adjustable piece of apparatus that mimics a rider’s bike position and allows that position to be optimised without the bike itself, and without the bike’s limitations.

Saddle position, handlebar position and crank length can all be experimented with while power, cadence, heart rate and torque vectoring are measured. Because nothing has to be swapped on a real bike, a rider can be optimised quickly and efficiently, without repeatedly changing stem lengths and handlebar widths. The jig costs around £20,000, which places it firmly in the professional workshop category.

Buying Advice: How to Decide What You Actually Need

Start with measurement rather than components. Feet should be measured and assessed before a shoe is chosen, and handlebar width and reach should be confirmed before short-reach levers or short-reach bars are considered.

Work through the cheaper and more reversible options first. Stem length is the usual starting point for reach, then bar width and bar reach, then lever body length. Riser bars and shorter cranks address front end height and pedalling mechanics rather than reach, so they solve a different set of problems. Pedal washers are inexpensive enough to try early if knee alignment or pressure on the outside of the foot is the issue. A fitting jig is a workshop investment rather than a home upgrade, but a session on one can confirm a position before any parts are bought.

Conclusion

None of these components is a universal upgrade. Each one exists because a specific group of riders has been poorly served by standard sizing: small riders who need narrower bars and shorter cranks, riders with wide feet, riders who cannot comfortably reach the brake levers, and riders whose front end needs to sit higher. Matched to the right problem, they make a position easier to live with. Matched to the wrong one, they simply move the difficulty somewhere else, which is why measurement comes before shopping.
