Q1. Can the CRM Track adaptors be retro fitted?
Yes. Track adaptors fit to standard CRM pedals. The only variation with factory prepared track pedals is the standard fitment of fixed pedal inserts. |
Q1a. Do the Track adaptors guarantee you can't pull your foot?
It is theoretically possible to still pull your foot but in practice it doesn't happen. There are 3rd`party items which provide additional security and more importantly, provide additional support for the shoe. Please contact Justin Grace at +64 21 324448. |
Q2. What is the stack height of the Keywin CRM?
The measurement from the axle centre to upper face of the shoe plate (cleat) is 17mm. |
Q3. What are the bearings used?
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). |

Q4. Is there an upgrade path from Speed Pedals and SL pedals to CRM?
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. |
Q5. Which axle length is right for me?
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. |

Q6. Do Keywin set a rider weight limit?
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. |
Q7. Do Keywin have a system allowing toe straps to be used for track use?
There is an aftermarket strapping system made by G-Race – email contact xxxx.
These have been developed by Justin Grace who has track raced very successfully in Australasia and USA as well as competing in the Worlds and Olympics. |
Q8. Can the Keywin Track adaptors be used in triathlons?
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. |
Q9. My Keywin shoe plates (cleats) do not follow my shoe curvature exactly.
What can I do?
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. |
