After the Eagle components have established themselves on the market, the Americans from 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 bottom bracket. SRAM DUB cranks have a standard shaft diameter of 28.99 millimeters.
Thanks to different variants of the completely redesigned and better sealed DUB bottom bracket, the cranks are compatible with all common bottom bracket shells. The aluminum crankshafts have also been redesigned, which means that the weight of the DUB crank sets could be reduced compared to their predecessors.
Made of aluminum 6000, the NX Eagle DUB crank arms also withstand occasional bumps and stone chips. The crank is complemented by the new X-Sync 2 Direct Mount chainrings. These impress with a significantly smoother 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 always keep the chain securely in place. The crank comes with a 32-tooth chain ring. You can find retrofit chainrings with 30 to 38 teeth in our shop.
