FSA KFX i28 Wheelset - 29" | Carbon | Hookless | 6-Bolt - 15x110mm | 12x148mm - XD

The i28 wheels extend the highly acclaimed KFX range from FSA with a product that was developed in collaboration with elite racer riders – including those from Cannondale Factory Racing Team – and combines cutting-edge technology with innovation tailored to the athlete. The centerpiece is the TOTAL CONTROL concept, which provides exceptional stability, responsiveness and precision for the toughest XC, XCO and marathon competitions.

While the carbon rims of the precisely handcrafted wheels with their asymmetrical construction and variable profile height improve both durability and handling, the aluminum hubs rely on the so-called Power Ratchet System (PRS), which is dedicated to optimized rolling characteristics. Its Helical Clutch Ratchet concept features 72 teeth, resulting in an outstanding engagement angle of 5 % and correspondingly responsive performance. In combination with the low weight, this results in a wheelset that has already proven its qualities by winning the Cross Country World Championship.
