FAQs

We've been producing virtually the same axle for over 25 years in chrome moly and over 15 years in titanium. We've had very few failures indeed. Our pedals are used by track riders a great deal and by many riding the kilo, which is arguably the greatest strain a pedal axle will be asked to take. These riders are often big guys with enormous power in their thighs. Many of them are 90+ kgs. The pedals have taken all this power with no problems.

This is a complex question involving personal preferences and other equipment on your bike.

The optimum solution is to have exact alignment of your hip, knee and ankle. The easiest way to judge this is to get someone to ride directly behind you for a short while and tell you whether your feet are being forced out wider than your hips (the most common situation).

If this test indicates you would be better with a narrower axle then check there is room in two places:
a) between the inside of the shoe and the crank and;
b) between your ankle and the crank with the radial movement in the most heel in position..

These two measurements are dependent on your set up i.e. the shoe width and your normal foot set up (toe in, toe out or parallel).

Keywin standard axle length puts the pedal centre at 55mm from the crank. Alternatives are 49mm (-6), 52mm (-3), 58mm (+3) and 61mm (+6). The most popular are standard and -3mm which we sell in about even quantities.

The wider axles are used predominantly by riders with wider feet and those who want clearance for over shoes etc.

The measurement from the axle centre to upper face of the shoe plate (cleat) is 17mm.

There have been some instances on not being able to tighten the cleat screws sufficient to stop the cleat rotating against some very slippery Carbon soled shoes.

This is easily overcome by adding a single strip of gaffer tape on the shoe sole to provide a key between the cleat and shoe sole. Once the cleat is attached in the correct position any tape extending beyond the cleat can be trimmed back.

The inner bearings are designated 63800 2RS (19mm x 10mm x 7mm with 2 rubber seals). The outer bearings are designated 698ZZ (19mm x 8mm x 6mm with 2 metal shields).

Yes! Track adaptors fit to standard CRM pedals. The only variation with factory prepared track pedals is the standard fitment of fixed pedal inserts.

Many top riders use the track adaptors to avoid delays during transition. But Keywin emphasise that track adaptors should not be used in their locked in position during any race on the road.

Unfortunately not all shoe soles are created equally. In most case a small deformation of the shoe plate does not affect performance. However it is best if the shoe plate is as close as possible to its natural curvature. Carefully cut and shape an old inner tube to the shape of the rear of the shoe plate to act as a packer. Sometimes two layers may be needed. Tighten the shoe plate to secure the packing rubber in place.

Yes, although to gain full radial movement some axles need a slight modification. If you are OK to continue riding with no radial movement, then no modifications are required.

Following rider requests, in late 2012 we made the clip out tension of both Carbon and CRM pedals slightly stiffer. This has been done by slight changes in the make up of the carbon and glass fibre reinforcing fibres used in the composites used in the pedal bodies. The result is now a clear “snap out” release.

The Keywin design depends on the two faces being kept reasonable clean and free of grit and sand. If grit and sand does get on these faces then there is a “keying” action which increases the release pressure required.

1. Cleaning is normally enough.

Simply keeping the faces clean ensures the release pressures do not become too high. The best way to keep the faces clean and the surfaces sliding against each other as designed is to polish the pedal body with ordinary shoe polish. Of course, this has the added benefit of keeping the pedal looking good.

2. Easy permanent release pressure reduction.

Increasing the bevel will also ease release pressure approximately in inverse proportion – i.e. double the height of the bevel will halve the release pressure.

Simply use a file to increase the height. The angle of the bevel is not critical.

We've had excellent reports from some common problems. Testers have reported relief to the extent they've have been able to carry on normal activities with tennis elbow; plantar fasciitis; sore knees; aching lower back; wrist pain like RSI; and stiff neck.
