I posted this similar thread in regular Road Bike but should have put it here. I am 205lbs ride 45-80km rides usually 4 days a week. I do not race, suppose it's sport touring with avg. speed of 28.5kmh. I do ride hard. Looking to get new bike and concerned about leap to CF or scandium. The 3 bikes I am looking at are Felt F4 or Look 555 (Both CF) or Colnago Strada (Scandium). Anyone have a ny good or bad experience with these bikes?
