I found my old Ritchey spd clipless pedals in the garage, the only problem was that one of the bearings had exploded. After a bit of measuring and internet investigating I found some sealed bearings that would fit (686-z 6mm – 13mm – 5mm) and gave the pedals a bit of a service then put them on my bike. Hopefully I can remember how to use them without falling off my bike like an idiot every time I stop.
