The most highly engineered compact wheels in the world. Immensely strong, inconceivably light, and with the added benefit of suspension. The front wheel is built around an ingenious suspension hub that provides 12mm of butter-smooth travel. Suspension is ultra-sensitive because the hub moves in the same path that road deformities impact the wheel. The hub soaks up vibrations and stays glued to the road - perfect when you have 125 psi in your tires and are riding over less than perfect conditions. Front and rear wheels feature custom rims made from a proprietary Niobium alloy and Sapim Laser spokes. The final touch is Rolf® Paired Spoke Technology™, the same wheel technology used by our favorite Tour de France winner. Patented technology.
