Lightweight clincher full carbon 36 mm deep rim for improved aerodynamics, increased rigidity and excellent inertia for sprinters and TT specialists. Easy to use Center Lock rotor mount for use with disc brakes. Stainless steel butted (2.0-1.8-2.0) and bladed straight pull spokes for optimal balance and rigidity.

Elbow-less spokes make for a strong yet compliant wheel. High lateral rigidity is produced with a wide flange spacing. Labyrinth double-contact sealing effectively shuts out water and dirt.

Alloy cone with integrated steel Borozon treated bearing races - super mirror finish reduces friction. Cold forged, machined aluminium hub shell and oversized 7075 alloy axle keep the wheel weight to a minimum.
