SRAM XX1 Eagle DUB Crank 1×12 | X-SYNC 2 SL Direct Mount Chainring 34 Teeth for Cannondale Ai | lunar-gray
After the Eagle components have established themselves on the market, the Americans of SRAM 2018 come with the next big coup for the further optimization of mountain bike drives. The DUB technology not only simplifies the combination of crankshaft and bottom bracket, it also ensures a higher durability of the inner bearing. SRAM DUB cranks have a uniform shaft diameter of 28.99 millimeters. Through various variants of the completely redesigned and better sealed DUB bottom bracket, the cranks are compatible with all common bottom bracket housings. The aluminum crankshafts have also been redesigned, reducing the weight of the DUB crank sets compared to their predecessors.
Through the use of the Carbon Tuned manufacturing process, the wall thickness of the XX1 Eagle DUB crank could be chosen at all points, so that it has a very high rigidity and yet is an absolute lightweight. The crank is complemented by the new X-Sync 2 SL Direct Mount chainrings. These impress with a much quieter running of the chain and better self-cleaning in muddy conditions. With the proven alternating thick-thin tooth profile, which is matched to the XX1 Eagle chain, the X-Sync 2 chainrings keep the chain always securely in place. The crank is delivered with a 34 teeth chainring. Retrofit chainrings with 30 to 38 teeth can be found in our shop. The crank is available with 170 mm or 175 mm crank length.
