Kestrel Superlight carbon layup gives the right blend of stiffness and compliance. 800K high-modulus carbon fiber used in the SL frames has a groundbreaking weight-to-stiffness ratio. The tapered (1-1/8 – 1-1/2) head tube increases lateral stiffness in the front end for better steering precision. A slightly sloping top tube allows the rider to mount and dismount more easily. The BB30 bottom bracket makes for a stiff and efficient pedaling platform.
Aerodynamic shaped stays, seat post, and seat tube, plus internal cable routing, let the wind slip over the bike. Geometry is aggressive, but with a bit more head-tube height and a shorter top tube for all-day comfort.
