The rim features a 65mm high and 26mm wide NACA profile.The wide, rounded shape of the Cosmic SL 65 rim was developed after many hours of wind tunnel testing to achieve the lowest possible drag without compromising crosswind stability. Its new, improved spokes allow it to save 80 g on its predecessor, the Comete Pro Carbon UST Disc. With the new profile of the rim's upper bridge, mounting tubeless or inner tube tires has never been so easy. Our new Infinity hub platform helps optimize shelving. The spoke tension, carefully adjusted, optimizes power transfer. The Instant Drive 360 freewheel body, combined with the automatic QRM Auto bearing adjustment, guarantees quick engagement, high rigidity and enhanced durability.With optimized spoke count and lacing, these wheels are specifically designed for disc brakes. Available for Center Lock system only, they are compatible with a 12mm thru-axle and convertible to quick release using the adapters provided.
