HK has several Look Keo pedals in various states of wear. Replacing the blade spring is trivial and that has been done as required but the pedal bearings are pretty rattly in a few of them and I would like to rebuild the pedals for a few years’ more use.
There are some replacement axles with bearings available for a wide range of prices but there are at least two incompatible axle lengths/ standards. I’ve not found model numbers for replacement axles online. How many axle standards does Look have? Is there a compatibility chart somewhere that says these types are interchangeable within the group, this other group’s axles are not compatible with the first group, etc.?
