I recently bought this bike for $20, and it was in working condition. I ride BMX most of the time, and know how to repair virtually everything on a BMX, so I'm not new to bikes, I just need some help with certain things. Also, I don't want to pour a bunch of money into this bike.
First of all, I accidentally crushed the threads on one of the cotter pins on the cranks. Should I buy new cotters or should I buy new square taper cranks? And if I get new cranks, how do I know what kind of spindle to get? (length, diameter, etc)
That's it for now, I'll be asking more questions as I continue working on this bike.
