Bianchi Oltre XR2
There might not be a single sharp angle on the sleek and curvy frame of the Oltre XR2. Every piece of this bike is designed to cut through the air from the deep wheels to the internal cable routing to the sculpted aero seat tube and seatpost. It uses the less common BB368 bottom bracket which is wider and therefore allows greater stiffness and more effective power transfer.
The ultra thin seatstays look almost flat, greatly reducing road vibration and increasing comfort although the bike still has a very aggressive riding position which will be uncomfortable for all but the most speed-minded rider. With the best Campagnolo components available, this is a racing bike with one purpose: to win.
