With TSE, the 858 NSW Carbon Tubeless Disc-brake wheelset features a tubeless and hookless rim profile for seamless tire interface and huge drop in weight. The 858 gives you the benefits of our deep rims at weight typically associated with rims that are 20mm shallower. The wheel’s internal width is 23mm, ideal for running wider tires with lower pressures for decreased rolling resistance. That’s how TSE technology helps you conquer the four barriers to speed: Wind Resistance, Gravity, Rolling Resistance, and Vibration Losses.\n\n The 858 NSW’s undulating 82mm-85mm deep rim shape, our patented Sawtooth profile, is our highest performing design for aero efficiency and crosswind stability. The result is the pure speed, especially for triathletes, time trial specialist, and any other speed freak. What’s more, while this wheelset is optimized for tubeless tires, you still have the option to run tubeless ready tires with tubes.\n\nThe 858 NSW is fastest with a 28mm tire. In triathlon, running wider tubeless tires at lower pressure makes you faster while also smoothing out the ride so your body is fresher for the run. Disc brakes also offer more reliable speed modulation and braking power in all weather conditions. The 858 NSW features the premium ZR1 SL hubset with ceramic bearings and 66 points of engagement.\n \n**Features**\n\n- Zipp’s most advanced and fastest deep-rim wheel for road, triathlon, and time trialing\n- More than 243 grams lighter that previous model\n- Optimized tire bed for easy tire installation\n- TSE for greater efficiency and reduced rolling resistance\n- Sawtooth rim with Hyperfoil nodes and HexFin ABLC dimple pattern for top aero and crosswind-stability performance with an undulating rim depth\n- ZR1 SL hubset with ceramic bearings\n- Ships with 12mm front and rear end caps\n- Center locking rotor interface.
