The Zipp 353 NSW Tubeless Disc Brake is the ideal wheelset for today´s endurance cyclists and road racers. Zipp´s most advanced in every performance area, the 353 NSW is also Zipp´s first SRAM AXS-connected wheel. Designed for racers, this lightweight climbing wheel features ceramic bearings and Zipp´s most advanced rim technology for impressive durability and aerodynamic performance. The 353 NSW rim seamlessly integrates the Zipp AXS wheel sensor for accurate tire pressure monitoring on the bike. It allows you to monitor and analyze tire pressure in real time without an external device attached to the valve. Accurate tire pressure adjustment helps cyclists optimize their speed and performance in a constantly changing riding environment. Before riding, immediately check the pressure, the green light means you´re good to go. During the ride, monitor the pressure to find the ideal setting and detect problems early. Zipp´s lightest wheel is even more powerful. A new design and carbon composition have improved the impact resistance of the already robust 353 NSW rim by more than 16%. With its 35/40 mm deep wave rim, the 353 NSW offers speed on valley roads, in the mountains, and downhill, with excellent rolling resistance, crosswind stability, and a light weight. The 353 NSW features the premium ZR1 SL hub with ceramic bearings and 66 points of engagement for a smooth roll. This hub is also 30 g lighter than the previous NSW wheel hub. The 353 NSW is optimized for 30 mm tires, and excellent options are available in the Goodyear Fitment Series for Zipp tires, manufactured exclusively for Zipp. The 353 NSW is not gravel-legal.Specifications:- Front Spoke Features: CX-Ray spokes - Black, aluminum nipples with Sapim Secure-Loc- Rim Color: UD fiber, Impress Standard technology- Crossing Rays: Crossed by 2- Front Axle Dimension: 12x100 mm- Discipline: Road- Product family: Wheels- Tidy: 353- Hub Range: ZR1 SL- Rim Height: 40 mm- Rim hook type: Carbon - Hookless- Outer Rim Width: 30 mm- Inner Rim Width: 25 mm- Rental: Before- Spoke length DS: 276 mm- NDS radius length: 278 mm- Axle material: Aluminum front & rear- Disk Mounting: Centerlock- Number of Front Spokes: 20- 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 HexFin- Axis Type: TA 12x100- Brake Type: Disc (CenterLock)- Tire Type: Tubeless
