TRUVATIV Crank Descendant Carbon Eagle DUB black 1x12 | X-SYNC 2 Direct Mount chainring 30 teeth for Cannondale Ai
The Descendant Carbon crank offers an unbeatable price-performance ratio. By using the Proprietary Carbon technology, the material thickness can be selected so that an optimal stiffness-weight ratio is achieved. The crank arms are very robust to be able to survive in rock gardens and tough trail use.
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. Thanks to 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 were also revised, which reduced the weight of the DUB crank sets compared to their predecessors.
The cranks supplemented by the current X-Sync 2 Direct Mount chainrings. These impress with a significantly 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 always hold the chain securely in place. The crank is delivered with a 30 tooth chainring.
NOTE: Contrary to the pictures, the crank is supplied with a chainring with 30 teeth.
