135? 142? 9? 15? 20? 100? 110?
What is the standard axel size for the next 5 years?
Are some of these new sizes the new standard or a passing fad?
So many choices to make.
None... but I'm betting 142x12 rear and 110x15 front for most new bikes. As for BB, standard english threaded is best I think and tappered steer tube.
