I loved my 46x15 ratio... but IRO cranks aren't a recommendation of mine...
I think I'm going to stick with my 42x15 for a bit, it makes me want to take off the front brake. In doing so, I want some shiny road bars to go with...I have a chrome fork, seatstays and chainstay. I currently have Nitto B-123s wrapped up with my front aero brake, and I absolutely hate them...not comfortable, not recommended at all. Any suggestions?
