Ok so I went to my LBS yesterday to check out bikes and sizes. I looked at Felt's, Treks, LeMonds, and some Cannondales. As I wrote in my other thread I am 5'10.5'' and have a 32'' inseam. So I tried out the bikes and the bike I am leaning towards (Felt F65) comes in a 54 and 56 which both fit me. As the guy at the shop told me, the 54 will be a bit quicker handling wise and give me more stand over clearance. The 56 on the other hand will have less room over the top tube, but it will feel a bit more stable on a long straight away and at higher speeds. So what should I do guys? This is going to be my first road specific bike. I have had mountain and hybrid bikes in the past, so should I go with the 54 as my first bike to build up some confidence?? Also, if I plan on doing some centuries in the future, wouldn't I want to have the larger bike? Or maybe not necessarily?
