In the process of overhauling a mid-70s bike for the
Quarantine Challenge, I’ve hit a minor snag overhauling these pedals (Mikashima Unique Road).
The cone for the pedal bearings doesn’t have a flat for a wrench, but instead a pair of indents on the back face. It appears the idea is that a special tool would hold the cone at the preferred preload while the lock nut was tightened.
Anyone have an idea what sort of tool I should be looking for to get these adjusted correctly? I’ve tried the Park pin spinners but the pins on those tools are too large.
Without a firm grip on the cone, it quickly over-tightens when the lock nut is tightened.
