I want to buy the Mercier Kilo TT Track Bike and was wondering what size would I be?
I'm 5'8 and my inseam is 30.I have a couple of friends who are basically the same height and inseam as me but one bought a 53cm and the other bought a 55cm.And another one of my friends is 5'9 with an inseam of 31 and got a 50cm.
Also what kind of lock should I get for commuting around school? I currently live in the resident halls, so at most I plan on leaving my bike outside 3 hours at one time. On average though my classes are about an hour or so. There are a lot of bikes on campus.
