Hey guys ill be stripping my bike down soon just like in Thump* s thread and will be doing a few little mods along the way. ill looking at getting a new 37t rear sprocket, atm i have a 420 pitch chain and sprocket but would love to put a 428 pitch chain and rear sprocket on because of the strength. Would this be okay? im thinking no because my front sprocket will still be 420 pitch and the rest 428? so ill have to upgrade my front sprocket to a 428 aswell yeah??
