I have some 170mm that are falling apart. I thought I'd try some 165mm because pedal-clipping is so scary, and expensive; last time it happened I broke my cell phone.
Anyway, I want something strong (I'm a heavy guy), under $50, and it needs to use a square-taper BB. What's my best option?
I've been looking on eBay and I found some Shimano Ultegra SL, Orgin 8/Bulletproof, generic cranks, and some Sugino RD2 (though, these are 170mm, but I here they're good).
Anyway, I also want to know if I should worry about the BCD. (I have a 52t chainring.) I think it's supposed to be as minimal as possible but is something as high as 144 all right?
