went out for about a 20 mile ride yesterday on the madone and thoroughly enjoyed it.. sure wish I would have had an opportunity for a more lengthy test ride on the specialized, but they didn't offer the demo to take home, and they were also 45 minute away from my house..
so i went with the trek madone 4.7 with the SRAM Rival group.. first set of bicycle shoes and clipless pedals too.. they freaking rock.
Thrilled with the whole setup.
thanks again for all the advice and thoughts!
