The undeniable speed of the 404 NSW platform is pretty mean on its own, but when you add tubeless compatibility and disc brakes, as the tubeless 404 NSW Carbon Disc Brake Road Wheel has done, then it gets even meaner. It's a an out-and-out race wheel whose braking and more reliable carbon layup mean it's not afraid to venture off the tarmac from some gravel time. The fact that it runs tubeless makes it even more eager to do so, as tubeless tires can ride with a lower PSI for more cushion, better grip on uneven surfaces, and less rolling resistance when you rejoin the road. They also puncture less, so dabbling in dirt isn't such a game of chance. Despite the advancements to rim, which is the element of the wheel that Zipp's tag line of "Speed Weaponry" is typically associated with, we're going to start here with the Cognition hub. Blasphemy, we know, but the Cognition makes a strong case for itself. We'd even go so far to suggest that the NSW's Cognition rear hub may be the most exciting innovation we've seen in factory wheels since Zipp first introduced its bulging sidewalls. The hub owes its sex appeal to Zipp's Axial Clutch freewheel design, 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 and engages from the inside out, the Axial Clutch's MIM rings engage laterally to reduce friction, so the engagement mechanism itself doesn't tax as many watts from your efforts. 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 for what may ...

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.
