I don't use these pedals but know plenty of you that do. I came across this interesting comment from the designer of the pedal that may be of interest if you use these:
- The reason the pedals need to be greased every ~5000 kilometers is because of the bearing design. Many pedals use cartridge bearings, but Speedplay uses needle bearings because of their higher load rating and better performance. The drawback to needle bearings is that they slowly push the grease out to the side, thus the need to regrease your Speedplays every so often.
Note: if the pedal spins nice and freely, this is a sign that it needs to be greased. The pedal should spin on the axel with slight resistance. This tells you the grease is doing it’s job.The complete article can be read here:
