I am 6'4" and weigh about 315 LBS. (Down from 340!) I am comparing a few different bikes and need some help for a tie breaker. I will mention that I just returned a Specialized Cross Trail Sport because it was terrible on a 30 mile ride. That and my buddy blew me away on his 7.5 FX. So, I need more speed and am considering Giant FCR 1, Specialized Sirrus Sport, 7.5 FX and Jamis Allegro 3. (The Allegro 3 has to be way better because it costs alot more.)
I tested the Sirrus which was quick but the components seem week compared to FCR 1. I tested an FCR 1 that rode well but the bike was too small because they only had a large available. I have to order the XL and may require a 10% deposit.
Can you provide advice? Also, should upgrade the rear wheel?
