Fulcrum  Racing Speed 55T Carbon Tubular Wheelset - Cult Bearings - Shimano

We spent hours and hours in wind tunnels. We studied the effects of rolling on the structure of the rim to make a wheel dedicated to the very essence of speed, when average speeds are really high and every watt has to count. The new 55 mm design is the latest response to the historic challenge of headwinds and attrition. Specifications: TYRE TYPE: Tubular TYRE SIZE: 28 WEIGHT: 1280 g.
