SRAM GX Eagle Dub 12 Speed Boost Crankset

With their striking shape, the GX Eagle crank arms immediately catch the eye. Made of 7000 aluminum, they can withstand occasional bumps and stone chips. The crank is supplemented by an X-Sync 2 Direct Mount chainring. This impresses with a significantly quieter running of the chain and better self-cleaning in muddy conditions. With the proven alternating thick-thin tooth profile, it holds the chain securely in place. The crank is delivered with a 32 tooth chainring. The bare aluminum teeth still look like new after thousands of kilometers, as unsightly, rubbed areas in the anodized coating are not possible. You can find retrofit chainrings with 30 to 38 teeth in our shop.

DUB technology not only simplifies the combination of crankshaft and bottom bracket, it also increases the durability of the bottom bracket. SRAM DUB cranks have a uniform shaft diameter of 28.99 millimeters. The cranks are compatible with all common bottom bracket housings thanks to various variants of the completely redesigned and better-sealed DUB bottom bracket. The aluminum crankshafts were also revised, which reduced the weight of the DUB crank sets compared to their predecessors.
