Just recently I fronted the money for a 2008 redline 925 for commuting. I'm not used to riding bikes like these because the only bikes I've had before this were cheap department store crap that never fit me right.

I am 5'9'' and I have an inner leg length of 32''. I did the equations online and the bike shop guy told me that i should have a frame size of 56cm. I rode both the 54 and the 56 and decided that the 56 was a little bit too big. Do they tend to be bigger than usual? Will I regret the 54 and need to go to the 56?

Thanks for the help
