We know you might be here to try Zipp’s recent batch of speed weaponry, the 303 NSW Carbon Clincher Road Wheel, but tarry for just a little and follow us back in time. The year is 2010, and the two greatest cobblestone riders of this generation are preparing to lock horns in yet every other season of pave monuments. Flanders used to be first, and when probably the most protagonists, Cancellara, rolled to the place to begin with 45mm carbon rims, we scoffed into our Duvel. Having been witness to the failure of carbon on cobblestones year after year, we thought that there used to be no way he’d live to tell the tale to Ninove without those wheels failing. And we were flawed. Resplendent within the Swiss champion’s jersey, Spartacus rode away in spectacular fashion at the Kapelmuur and never looked back. Zipp’s 303 platform is the wheel that made the carbon/cobbles marriage a reality, and the event is immortalized by images of Cancellara rolling down the finishing straight even as defiantly waving a tiny Swiss flag against a backdrop of countless Flandrian and Belgian flags. The combination of aerodynamics and reliability meant that carbon no longer had to fear the stones, and the 303 NSW represents an immense update. It is more aerodynamic, brakes better, and is much more reliable than before. And that is the reason just the rim. For the first time in its lifespan, the 303’s new hubs are each and every bit as impressive as its rims. We admit that we haven’t at all times associated Zipp with hub innovation, however the 303 NSW’s Cognition rear hub is also probably the most exciting technology in factory wheels that we now have seen since Zipp first introduced its bulging sidewalls. The freehub is centered on Zipp’s Axial Seize 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 one another even as freewheeling but engage every other throughout pedal input. In comparison to an ordinary pawl design, which in truth resembles a drum brak…
