I am very proud to say I seem to have worn out my pedals. The left pedal started locking up when I was pedalling. So I took the pedals apart, cleaned all the parts and the bearings, greased it all up well and put it back together. The right pedal is not too bad, but I don't think I got the locknut on quite right. I assume there is a special tool out there? On the left pedal, all the bearings had rusted. Even after a thorough cleaning, they looked tarnished and rusted. And the pedal is still locking up after I've greased it and put it back together. So my question is, is it worth getting new bearings and attempting to repair the pedals? Will I ever be able to put them back together right? I stopped by one bike shop this morning on my shopping round and asked about it and the guy said they wouldn't be worth repairing (I didn't have the pedals with me to show him). He says he wears out a pair of pedals in just three months and has to just replace them. I've had mine for almost a year.....I'll ask at another bike shop this afternoon, but thought I'd ask your expert opinions too. A new set of pedals are a bit on the pricy side for me, especially if I have to buy new ones every year.
