I'm building myself a roadie as a training bike for fitness mainly.
I've been handed down a litespeed frame from a friend, with a post and some bits, but i need to buy a chainset and some other bits like STIs.
I've always run 175mm arms on my MTBs, but the roadie ones seem commonly to be 170 or 172.5, and i'm not sure what to get, I'm 5ft 11 with a 32" inside leg if that helps?
Also, i'm shopping around for prices for some STIs and chainsets, 5700 105 seems to be cheaper than 5600, 5700 being the replacement for 5600 right?
thanks!
