Cycling lore is filled with mountain goat climbers flying up passes on wheels measured against feathers. Zipp brings legend to the road with its mountain conquering 202 rims for those of us looking to step up our climbing game. Don't be fooled by its featherweight status though, the Zipp 202 Firecrest Carbon Road Tubular Wheelset is a versatile set of hoops that dives downhill and rolls the flats as an efficiently solid all around workhorse. The 202 Firecrest features Zipp's lowest profile rim. At just 32mm, the 202 platform enjoys exceptional crosswind stability compared to its deeper stablemates. A wide, 24. 62mm brake track accommodates a variety of tire widths to match different racing styles and road conditions and provides a solid platform on which to mount your favorite tubular tire. Zipp's wind tunnel testing shows that the 202's 32mm U shaped profile cuts through the air on flat ground as efficiently as most other 45 50mm rims, with the added advantage of a feathery light 1,180g weight so they practically fly away when the road starts climbing. Rail the course with confidence that these wheels will hold pace with the deep dished aero setups and climb away like a mountain goat when the moment calls. As an added aerodynamic bonus, an updated version of Zipp's signature Aerodynamic Boundary Layer Control ABLC dimpling uses strategically placed and sized dimples across the rim surface to smooth airflow and manage drag causing turbulence. ABLC also boasts aerodynamic advantages at real world yaw angles of ten to 20 degrees, comparing favorably with many competitors whose minimum drag numbers at yaw angles of five to ten degrees rarely occur outside of a wind tunnel. In less scientific terms, these wheels perform best in the windy conditions you'll actually encounter out on the roads. At the center, Zipp uses its updated 77177 hubset with improved stiffness and durability over its predecessor for a smooth, supple ride. With a new platform and graphics fo...
