AX Lightness Premium 55T Tune Hub Tubular Wheelset

AX Lightness's Premium 55T Tune Hub Tubular Wheelset is designed to plow through the wind with the same enthusiasm with which Admiral Farragut once famously confronted torpedoes. Given that he was in a boat at the time, the Admiral's storied bravery may have been on the foolish side however, the Premium 55Ts benefit from the same fluid dynamic considerations AX Lightness pours into its motorsport designs, so their wind be damned attitude is based purely on science, not hubris. Most 55mm rims offer recognizable benefits when the yaw angle is low, but they turn erratic when the angle gets obtuse, throwing the bike and its rider around the road. As illustrated by the peculiar shape of their rims, the Premium 55Ts don't rest on these kind of wind tunnel only aerodynamics. The cross section swells to 26 millimeters at its widest and terminates in a blunt, round shape rather than a point, which keeps unruly laminar air in check as it travels across the rim's surface. This eliminates pockets of dead air while rolling forward, and it also refuses crosswinds any purchase, keeping the handling consistent and predictable under conditions turbulent enough to sink any other 55 millimeter wheels. While that combination of aerodynamics and handling in crosswinds eliminates the typical drawbacks of deep rims, stiffness and weight are still important aspects of any racing wheels. AX Lightness uses a carbon weave for the rims because, unlike the ubiquitous unidirectional fibers of late, a woven fabric has load bearing properties that recommend it for a wheel's rim, which experiences dynamic directions of pressure as it spins. This means efficient power transfer and torsional stiffness can be achieved with less material, which in turn results in less weight. The Premium 55Ts enjoy the universal technology of rim construction that defines AX Lightness, including AX Lightness's Seamless Brake Surface SBS. SBS uses high pressure autoclaves to combine the wheels' layers with ...
