The new Gossamer Pro ABS duralumin road key model is conceptually based on the carbon top models FSA K-Force Light ABS and SL-K Light ABS. It excels in excellent rigidity, low weight and great compatibility.
The cranks use a new technology of arm distribution - ABS (Asymmetric Bolt Standard), which guarantees increased rigidity and thus more efficient transmission of forces during grip. The single BCD 110mm allows the assembly of all manufactured combinations of ABS converters on one key model (53/39, 52/36, 50/34, 46/36).
The new CNC-machined duralumin converters made of AL7075 material with improved ramps and modified tooth shape for the fastest and most accurate shifting have also undergone significant changes. The cleanliness of the keys is achieved by using hidden screws to fasten the transducers.
The 386EVO integrated hollow duralumin shaft made of AL7050 material with a diameter of 30 mm also contributes to low weight, increased rigidity and at the same time ensures compatibility with almost all available frames on the market (386EVO, BB-30, PF-30, threaded BSA, BB-86) . The middle composition must be purchased for a specific frame model.
The cranks are compatible with all 10 and 11 speed systems (Shimano, Sram, Campagnolo). Q-Factor 145mm. Weight 750g.
