Jean, Are those 2.0" tires? I"m curious if they make any noise or noticable buzzing while riding unloaded. I've got a 35mm Marathon supreme on the rear of another bike that's starting to get squared off with wear. The 1.75" Panaracer T-serv tires have kind of a rounded trapezoid shape like the BigApples but I think there's a squeeging action in the tread that makes them slower than the 35mm T-servs or the Supremes. The tires feel well connected to the road but I bet the Supremes are just as connected with less rolling resistance.

Mine is also black, set up with drop bars about 1" below seat height, a generator front hub w. Dyad rim and rear wheel with a beefy Rhynolite rim. Two rolls of black cloth tape wrapped on the top tube so I don't care about leaning it up against metal poles.
