Cliking noise from SPD. Need HELP!
Hi folks, not much chat on here these days which is sad to see but hopefully someone replies to this....
I recently installed some Shimano m520 spd's and they were going fine up until a few weeks a go. The left pedal has developed this awful loud clicking noise on the down stroke. I have taken it off and lubed the whole pedal and the cleat on my shoe but that didn't do anything. One thing I did notice is that it only happens when sitting down and pedaling, it doesn't happen when standing and pedaling. I have checked for lose chain ring bolts, seat posts etc but I'm fairly sure the noise is coming from the left pedal. I can actually kind of feel the click through my foot.
Any ideas what could be causing this horrendous noise?
