Meticulously tested with CFD software to be as aerodynamic as possible, but also proven fast in the real world- on the road. Built with our proprietary rim and hub designs, using ceramic bearings, and Sapim CX-Ray spokes for light weight, and durability. Combined with our 3-pawl, 51 ratchets freehub for near-instant engagement, the AON TLR 60 wheels are designed for outright speed.
