Heres a great cycling tip for everyone, reset you computers for metric. Having just finished a ride in the US where everyting is in miles, and coming from "the Great White North" where everything is in Kilometres. I feel I can make an observation:
Miles per Hour sucks when you are on a bike!!!!! I know is all in your head, but in Kilometres per Hour, things just go by faster, you go faster and you ride further! Try it!
