A short video on how to replace a tub spout
Shimano SPD m515 pedal.
Servicing the bearings, disassembly, clean, grease, reassemble.
If you are able to service the pedal, I mean if you have tools and some experience taking things apart and putting it all back together correctly or it might be better to just buy new pedals. I have 20,000 miles on this set of pedals and they still spin smoothly. The cleats are wearing out though. might be time for new pedals. Read more below.
