I am running out of one piece chain rings, I have a couple with bunged up threads. First does anyone know for sure what the pedal thread pitch is. I found that a 12mm x 1 nut (hopefully nuts weren't mixed with 12mm x 1.25 nut) fits perfectly on the pedal also a 1/2 in x 20 tap appears to work fine, just touching the threads, Where do I find suitable left and right hand taps, Carpe Ductum
