Zipp 454 Nsw Zr1sl 12s Cl Disc Tubeless Road Wheel Set. Unleash your speed with the Zipp 454 NSW ZR1SL 12s CL Disc Tubeless road wheelset. Engineered for peak performance, its revolutionary 58mm Sawtooth wavy rim with Hyperfoils offers unparalleled aerodynamics and stability in any condition. Designed for tubeless tires at lower pressures, it minimizes rolling resistance and vibration, ensuring maximum energy transfer. The hookless rim design further enhances aerodynamics and strength. Paired with the premium, lighter ZR1 SL hub featuring ceramic bearings and 66 points of engagement, these wheels are built to conquer the road. The Zipp 454 NSW Tubeless Disc-brake wheel is the ultimate road racing wheel. It meets the demands of the performance cyclist. Aerodynamic and stable in all weather, it features a wider rim designed for lower-pressure tubeless tires, reducing rolling resistance and vibration. This means you´ll lose as little energy as possible on the road. For the optimal combination of aerodynamics and rolling resistance gains, a 28mm tire is recommended. Its 58mm Sawtooth wavy rim with Hyperfoils is our most aerodynamic and stable wheel yet. The 454 NSW benefits from Zipp´s Total System Efficiency (TSE), our approach to combating the greatest enemies of speed: wind resistance, gravity, rolling resistance, and vibration. And gravity? Zipp´s use of hookless (straight-sided) rims on the 454 NSW is essential to the ´´You Faster´´ strategy. This technology makes the transition between tire and rim smoother and more aerodynamic. Zipp hookless rims benefit from more efficient resin distribution, resulting in lighter and stronger wheels. The 454 NSW features the premium ZR1 SL hub with ceramic bearings and 66 points of engagement. This hub is also 30g lighter than the previous NSW wheel hub.Specifications:- Rear Spoke: CX-Ray spokes - Black, aluminum nipples with Sapim Secure-Loc- Front Spoke: CX-Ray spokes - Black, aluminum nipples with Sapim Secure-Loc- Rim Color: UD fiber, Impress Standard technology- Crossing Rays: Crossed by 2- Rear Axle Dimension: 12x142 mm- Front Axle Dimension: 12x100 mm- Discipline: Road- Product family: Wheels- Tidy: 454- Hub Range: ZR1 SL- Rim Height: 58 mm- Rim hook type: Carbon - Hookless- Outer Rim Width: 28 mm- Inner Rim Width: 23 mm- Rental: Peer- Spoke length DS: 254.2520 mm- NDS radius length: 256 mm- Axle material: Aluminum front & rear- Hub material: Aluminum- Freewheel mechanism: 6-pawl compression, 66 points of engagement- Disk Mounting: Centerlock- Number of Rear Spokes: 24- Number of Front Spokes: 24- Maximum recommended total weight: 250 lbs / 114 kg- Maximum pressure: 73 psi / 5.0 bar- Rim Profile: Symmetrical- Hub Bearing: Cartridge - Ceramic- Size Diameter: 700c- Surface texture: ABLC Sawtooth- Axis Type: TA 12x100 & TA 12x142- Brake Type: Disc (CenterLock)- Tire Type: Tubeless- Freewheel Type: SRAM XDR. tradeinn Bikeinn
