To further improve the wheelset’s rolling efficiency, the 202 NSW rim is laced to their groundbreaking Cognition hubset. Knowing that there is no benefit to a wheelset that climbs fast and descends slow, NSW engineers incorporated their Showstopper brake track for the most confidence inspiring rim braking performance available, whether the road is wet or dry. Then they reduced aerodynamic drag with ABLC Sawtooth technology and used ImPress graphics to ensure that nothing stood between the air flowing over the rim and the dimples made to smooth that flow. With a new lighter carbon fiber layup for the 32mm deep 202 NSW, they’ve dropped weight where it matters most, at the outer edge of the wheel, while maintaining the durability and lateral stiffness that Firecrest is famous for. This is why Zipp engineers in The Nest chose to enhance the world’s fastest climbing carbon clincher, the 202 Firecrest. In order for a climbing wheelset to be world beating it has to do more than simply deliver low weight it has to deliver uncompromising performance on every level. And because extracting greater speed on the mountain is only half the battle, they built the 202 NSW to deliver the lowest aerodynamic drag available for a rim of this depth for speed everywhere else. But the NSW advanced development team delivered on every request and built the ultimate climbing wheelset, a climbing wheelset strong enough to use on every ride.Įngineered to be the fastest accelerating carbon clincher Zipp has ever made, 202 NSW flies up the toughest climbs, and then shaves even more time off of the descents to follow. When they asked them to do all of this without sacrificing durability, it looked like an impossibility. When Zipp gave their top engineers in The Nest advanced development lab the task of shedding more weight from their lightest carbon clincher wheelset, the 202 Firecrest, while also improving rolling friction, aerodynamics, and braking, it was a very tall order.
