The Zipp 404S Tubeless Disc C.L. XDR 12X142 50mm Rear Wheelfeatured here at Escapa has been developed for road cyclists who want to take a real leap forward in speed, efficiency, and aerodynamic performance. With a 50mm profile, it offers an excellent balance between aerodynamic penetration, lightness, and stability in crosswinds.
Inspired by the Firecrest design used by Zipp in WorldTour competition, they bring high-end performance to a more accessible option within the brand’s lineup. Compared to the Zipp 303 S, they offer an approximate aerodynamic advantage of 2 watts, along with a more specific focus on performance on asphalt.
50 mm Profile for Faster Riding
The 50-mm-deep carbon rim is optimized for maintaining high speeds on the road. Its mid-depth profile delivers aerodynamic gains without the increased sensitivity to crosswinds found in deeper-profile wheels.
This configuration makes the 404 S a versatile wheel for fast rides, races, triathlons, gran fondo events, and routes that combine flat terrain, climbs, and descents.
Wide rim for modern tires
The 23 mm internal width allows for better utilization of today’s road tires, providing more stable support, an optimized tire shape, and a more controlled ride.
The Hookless Tubeless Straight Side construction is designed exclusively for tubeless-compatible tires. This configuration allows you to ride at pressures tailored to your weight and the Terreno, improving comfort, grip, and resistance to pinch flats.
Zipp 176D Hubs
Features Zipp 176D hubs equipped with sealed stainless steel cartridge bearings. The rear hub offers 36 engagement points, providing quick response when resuming pedaling after a turn or during a change of pace.
Sturdy and Efficient Spoke Pattern
The Zipp 404 S uses a 20-spoke, two-cross lacing pattern with aerodynamic Sapim CX-Sprint spokes. This construction is designed to offer a balanced combination of lateral stiffness, durability, and responsiveness under load.
