Faster uphill and acceleratingIncreased lateral rigidity for improved power transfer Improved UST offers more speed, comfort and controlWith quick acceleration and a lightweight, efficient feel on the climbs, this newcomer in the Cosmic family takes over the venerable Ksyrium Pro Carbon UST. Carbon rims and disc-brake control give you an added advantage in the mountains and hills. It features the same rim as our pro-level SLR 32 model, which means superlight full carbon construction for easier climbing and instant acceleration.Key Features:Faster uphill and acceleratingReduced inertia of a lighter weight rim delivers instant accelerationNACA inspired rim shape (32mm deep) minimises aerodynamic dragFlat double-butted spokes save weight and improve responsivenessLaterally stiff for improved power transferInfinity hub platform optimises lacing and spoke tension to improve wheel stabilityStrong hub axle and ID360 freewheel technology for instant accelerationImproved UST Road delivering spe
