Fulcrum Speed 55T Tubular Wheelset - 2018

The new Fulcrum Speed 55T Tubular Wheelset has a deep profile, one that offers not only extreme aerodynamic advantages but also a larger rotating mass capable of retaining the high speeds of flatter races, time trials and triathlon cycling legs. Despite their deep profile seemingly adept at flatter terrains the 1470g weight for the pair make the 55T a viable solution even for those courses with a great deal of climbing. The internal width makes these wheels perfect for 25 and 28mm tires, for surefooted high-speed descents and cornering.

New Carbon Rim

New fibres and orientations have been implemented to push the limits of the SPEED family even further. While the new “longitudinal twill” design of the fibers offer a fresh and new look, the aesthetics advantages come about as a convenient by-product of engineering a stronger yet more elastic complete final structure. The result is a resistant and reactive rim that is also capable of absorbing road vibration, thus keeping the rider fresher and better connected to the road. To keep the look consistent this new and advanced carbon layup finds itself implemented into the construction of the front hub as well.

AC3 Brake Surface

In addition to keeping the SPEED family wheels moving forward, a great deal of research and development has gone into slowing them down. A fast wheel is only as good as the control it offers to the rider and the all-new AC3, or ALL CONDITIONS CARBON CONTROL, brake track technology incorporated into the 55C offers unprecedented braking performance. The new technology incorporates laser treatment upon the brake track, eliminating all traces of resin, and allowing pads to brake on a more surefooted and planar carbon surface. While braking performance improves across the board, in wet conditions the AC3 excels with stopping distances more than 30% shorter when compared to previous versions.
