Bottom bracket
Hey guys;
The bottom bracket on my bike is rusted/stripped out/crappy. I'm in the market for another one but I'm a little confused about the sizing. I currently have a 68x121.5. Can i get a 122? 118? Whats going to be the noticeable difference if the length changes. Also, I'm in the market for a single speed crankset, any suggestions?
Thanks,
Up.
