Zipp: ADVANCED DEVELOPMENT DEFINEDLight enough to fly up climbs, tough enough to excel in the cobbled classics, and with the industry’s best available braking performance for the most technical descents, the 45mm deep 303 NSW is built for a singular purpose: To be fast, everywhere. But the 303 NSW is no ‘race day only’ wheelset to be tucked away in a wheel bag until a race number is pinned to the rider’s jersey. It’s built to take the abuse of everyday training rides. Zipp has achieved this reliability at a lighter weight with a revised carbon fiber layup developed through testing on the famed cobbles of the Arenberg Forest with the world’s fastest riders.THINGS TO REMEMBER45 mm rim depthCognition™ Disc-brake hubsetAxial Clutch™ technologyImPress™ GraphicsABLC SawTooth™ Dimple patternTubelessCarbon ClincherDisc-brakeAeroBalance™Handcrafted in the USAFEATURES AND BENEFITSSuperior modulation and stopping power of disc brakes.303 NSW® rolls efficiently whether you are pedalling or coasting. Our Axial Clutch™ technology allows the freehub’s ratcheting mechanism to deliver half the mechanical drag of conventional three-pawl hubs.We’ve employed Zipp’s ImPress™ graphics technology, which prints graphics directly on the wheel, to help allow the dimples to do what they were designed to do – control vortex shedding, the rate at which air sheds off the wheel.Tubeless ensuring secure performance even when ridden at lower tire pressures.SPECIFICATIONSSize (wheels): 700cRim construction: CarbonRim - inside width: 21mmCompat - Tire: Clincher Tubeless ReadyBrake compatibility: Disc (Center Lock)Cassette Compatibility: Campagnolo, n/a, SRAM XD-R, SRAM/Shimano RoadAxle type (Wheels): Conversion Caps includedColour (Decal): ImpressDriver Mechanism: Axial Clutch, n/aSpoke count: 24Spoke type: CX-Ray - BlackBearings: Cartridge - Stainless SteelNipple material: AluminiumRim finish: UD fiber, Impress technologyRim section: AsymmetricalSpoke pattern: 2 Cross
