Zipp 303 S

The new Zipp 303 S disc brake wheel offers modern road and gravel bike riders the versatility and speed they need to reach their top speeds.The new wheelset retains its ideal rim height of 45 mm and has an internal width of 23 mm.The 303 S is one of the lightest Zipp wheels optimized with a 28 mm tire for maximum aero performance, but can also be used with gravel tires up to 50 mm wide. The overall 27mm wide rim, which is also tubeless capable, optimizes the tire shape to allow for lower tire pressure. This reduces rolling resistance and allows a savings of 10 watts over a comparable high-end wheelset in the total power required to ride 40 km/h on a flat road with a 28 mm tire. In addition, the Zipp 303 S come in a completely new look. - Design: rear - Purpose: road bike - Axle system: HR 12x142 mm mm - Details: - Maximum tire pressure 73 psi - Maximum rider weight 113 kg - Campagnolo freewheel sold separately - Axle standard: thru axle rear hub - Rear axle diameter: 12 mm - Installation width: 142 mm - Sprocket type: SRAM XDR 12s - Type: 176D - Number of spokes: 24 - Features: sealed Rims - Height: 45 - Tire type: clincher/Clincher - Construction: hollow chamber - Brake system: disc brake - Tubeless suitable - Width: 27 mm - Tread height: medium (30 - 50mm) - Material: carbon - Size (in inches): 28 inch - Width of jaws: 23 mm Included in delivery - Scope of delivery: centerlock lock ring, tubeless valve, valve wrench, tubeless rim tape Spokes - Construction: spokes: CX-Sprint / Nipples: Sapim Secure-Loc - Lacing: 2-fold crossed rear wheel - Designed for brake type: disc brake Center Lock - Weight: 819 g.
