SRAM NX Eagle DUB Fatbike Crank 1x12 | FAT4 X-SYNC 2 Direct Mount Chainring 30 teeth
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 over their predecessors.
Made of aluminum 6000, the NX Eagle DUB crank arms can withstand occasional pegs and rockfalls. The crank is complemented by the new X-Sync 2 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 Eagle chains, the X-Sync 2 chainrings keep the chain always securely in place. The crank is delivered with a 32 teeth chainring. Retrofit chainrings with 30 to 38 teeth can be found in our shop.
NOTE: You can find the suitable for your frame DUB bottom bracket and other chainrings in our shop.
