454 NSW Carbon Clincher Disc Brake Road Wheel by Zipp
If you'll forgive us the pun, we think it's safe to say Zipp made a splash with the release of the 454 wheelset. After all, the brand used biomimicry and looked to the sea when seeking new aerodynamic inspiration for this wheelset. The 454 NSW Carbon Clincher Disc Brake Road Wheels features a unique, alternating rim shape inspired by the tubercles found on the edges of humpback whales' fins for a rim profile that maximizes aerodynamic benefits at all yaw angles and increases crosswind stability when those angles get steep. The most immediately 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 any given speed compared to even the 404 NSW. The 454 NSW also marks a departure from Zipp's signature dimpling, upgrading the ABLC design to HexFin ABLC. The HexFin ABLC dimples take inspiration from their round predecessors' claimed ability to better manage the boundary layer of air against the rim, but Zipp tells us that the updated, hexagonal shape enjoys yet more of the stable aerodynamic benefits associated with the now-traditional round dimples. Further departing from the all-over dimpling of Zipp's other wheels, the 454'...

Rising above a scene rich with extraordinary wildlife, pristine lakes, and alpine terrain, the Teton Range stands monument to the people who fought to protect it. These are mountains of the imagination. Mountains that led to the creation of Grand Teton National Park where you can explore over two hundred miles of trails, float the Snake River or enjoy the serenity of this remarkable place.
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.
