Why else would the pedal fall off whilst I'm cycling? I would assume forward motion on a bike would increase resistance between pedal and the crank, not loosen it? Come to think there was a bit of resistance on the R pedal's spindle when rotating it, it was not turning as easy as the L pedal. I tried to lube it up but still the same. I guess it doesn't matter now lol so I will just get a new pair.
Does anyone recommend a place to get reasonably priced vintage pedals for a pinarello? These were from eBay..
