Product Description
454 NSW Carbon Disc Brake Wheel - Tubular by Zipp
Never one to rest on its laurels, Zipp is in a never-ending quest to increase wheel aerodynamics without coming at the expense of crosswind stability. What's often perceived radical and avant-garde in its design infancy often becomes the norm down the road. Take for instance its broader, rounded blunt-nosed rims design a few years ago. A quick look reveals that many brands now have adopted the shape. Its latest design, however, is something entirely different. The Zipp NSW Carbon Disc Brake Wheel features a unique and variable rim design using biomimicry and inspired by that of a humpback whale. It's unique for sure, but no one logs wind tunnel time like Zipp and it found that the tubercles on the edges of humpback whale fins were beneficial when creating a rim profile that oscillates with its depth, thus it uses a striking shape that Zipp claims increases aerodynamic benefits and boosts the brand's already notable crosswind stability.The most obvious difference between the 454 and any other wheel is in the rim shape, whose depth varies between 58mm at its deepest point and 53mm at its shallowest in a series of wavy swells Zipp refers to as Hyperfoils. The overall design is known as SawTooth, which takes on a shape not dissimilar to the ABLC SawTooth dimple patterning found on the 404 NSW. These bumps, designated as Hyperfoils, are meant to mimic the nodes or tubercles found on the fins of humpback whales that manage water resistance and contribute to the massive animals' ability to swiftly maneuver despite their size. Compared to standard, consistent depth rims, Zipp claims that wind tunnel testing shows that this SawTooth design significantly reduces both side force and aerodynamic drag, which in combination should translate to more confident handling when riding on exposed roads in variable winds and an easier time pushing the pedals at any given speed compared to even the 404 NSW.The 454 NSW also marks a departure from Zipp's signature dimpling, upgrading t...

Featured Wildlife
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.
