Product Description
303 NSW Carbon Road Wheel - Tubeless by Zipp
Ever since its inception in 2015, Zipp's NSW Series has been the launching pad for Zipp's most relevant innovations. And to that end, the Zipp 303 NSW Carbon Tubeless Road Wheel features an entirely redesigned rim shape that aerodynamically integrates wider tubeless tires for enhanced ride quality and performance. The 303 NSW Carbon Tubeless features a wider 19mm internal rim width and corresponding outer rim shape for aerodynamic optimization with 25mm tires. This wheelset allows you to run tubeless or traditional clinchers. The benefits of tubeless include superior flat protection, the ability to run lower pressures, and a smoother ride with high cornering grip and low rolling resistance. The 303 NSW represents a major update--it's more aerodynamic, brakes better, and is even more reliable than before. And that's just the rim. For the first time in its lifespan, the 303's new hubs are every bit as impressive as its rims. We admit that we haven't always associated Zipp with hub innovation, but the 303 NSW's Cognition rear hub may be the most exciting technology in factory wheels that we've seen since Zipp first introduced its bulging sidewalls. The freehub is centered on Zipp's Axial Clutch mechanism, which features two Metal Injection Molding (MIM) ratcheting rings--one mated to the freehub body and one mated to the hub body. The two rings are machined like a ratchet, so they ramp off of each other while freewheeling but engage each other during pedal input. Compared to a standard pawl design, which actually resembles a drum brake, the Axial Clutch's MIM rings engage laterally to reduce friction while freewheeling, so coasting doesn't negate watts already spent. We're familiar with this model, as we've seen similar mechanisms on the designer hubs featured in top-end custom builds for years now, but Zipp is the first to replace the usual tensioning agent, steel springs, with magnets. This substitution further reduces friction between the ratcheting rings, making f.

The pika is a close relative of the rabbits and hares, with two upper incisors on each side of the jaw, one behind the other. Being rock-gray in color, pikas are seldom seen until their shrill, metallic call reveals their presence.
