Can I replacing the internal bearings, bushings and seals?
Yes, the pedals are very easy and fast to rebuild. the only tools necessary are a flat head screwdriver and a 3mm allen wrench to replace the sealed ball bearing and bushing. We offer $15 rebuild kits for each pedal that include bearings, bushings, seals and endcaps.
I suspect that the whole end needs to be removed and the bering then pushed out from the "inside".
