Product Details

2011 Ellsworth Coefficient (SRAM Force)

Made from full high-modulus carbon in a green, sustainable facility, Ellsworth's Coefficient is your best friend out on any course. This aero TT machine concentrates on 3 things: aerodynamics, energy conservation and fit. Using aero tubing, wheel cutouts and a carbon aero fork, the Coefficient is stealthy and fast. The carbon frame damps vibrations to reduce fatigue and the geometry and reversible aero seatpost make it easy to dial in a perfect, power-producing position. The spec is all about speed, too. SRAM Force and 900 TT components shift and brake with precision and transfer every watt of your power to the wind-cheating Zipp 404/808 wheelset so you'll have no trouble shattering old split times on your way to glory.
