XX Q-Factor SRAM cranks offer amazing performance and durability, with very low weight.
XX Q-Factor SRAM cranks offer amazing performance and durability, with very low weight. The first MTB crank designed specifically for 2x10. The large CNC plates, 6 mm 7075 aluminum, are 2 mm thicker than those of the competition, with une equal rigidity thanks to the larger bolt diameter (BCD) and a two-piece construction with carbon composite inserted. Crank XX geometry provides a narrow Q factor of 156 mm, with an efficient chain line to maximize separation.
For the BB30 bottom bracket system which, in addition to weight savings, reduces the Q factor by leaving more space between the rider's ankles, with greater bearing durability and reinforced crankshaft construction.
X-Glide technology allows you to change more easily at any time and in any direction, thanks to its new geometry for perfect chain-dishe harmony. By aligning the plate on the chain pivot, you get a very significant improvement in change.
