I know enough to know I don't know enough. Apparently my 83mm isis bb is going the way of betamax. Now I'm shopping for a whole new crank setup. So...what to put on my 05 Sunday now? 83mm bb, and 150 rear(if that matters). Weight is low on my list of priorities. I want to FR, and race DH without worrying about my cranks or bb. I'm about 170lb, ex bmx racer which everyone says they can tell by how I ride. Hmm? Anyone see any crankset deals that I can snap up? :thumbsup: Anyone??? Thanks in advance! I'm having a hell of a time shopping because I don't understand most of the numbers and jargan...so I don't know what will fit.
