This fantastic tubeless ready back roller offers big performance across a multitude of terrains, thanks to its lower tyre inflation adaptability and its optimised build. A carbon-built, 45mm rim profile provides more than ample aerodynamics and crosswind stability, aided by ABLC Sawtooth dimpling to shed air efficiently and effectively, letting you speed on with freedom and confidence.
Built specifically for use with disc brakes and wider tyres, it offers the powerful stopping and control expected from modern riders as well as low rolling resistance for the smoothest of runs. Spinning on Cognition Hubs, drag when coasting is further reduced, while the 21mm internal rim width assists in making this a speedy wheel consideration for various riding styles.
ABLC SawTooth Technology (Aerodynamic Boundary Layer Control): Zipp's new Sawtooth dimple design consists of 12 nodes that are specifically clocked to start aerodynamic shearing at a rate of 50hz at a rider speed of 20mph. Sawtooth accomplishes this by inducing small sheet vortices that shed at a low magnitude, but at a higher natural frequency, thus decreasing the laminar bubble effect on the aerodynamically shielded side of the rim’s profile to further reduce high yaw drag and improve crosswind stability.
