Detail Information

The SRAM Rival Direct Mount Crankset are a lightweight yet rugged set of cranks that prove that it is possible to upgrade the looks, comfort, and performance of a bicycle all at once. Sculpted and skeletonized aluminium crank arms are joined to SRAM's proven DUB bottom bracket spindle to provide incredible efficiency and power transfer to the rest of the drivetrain. One-piece, direct mount 2x chainrings utilize aggressively sculpted shift ramps, shifting pins, and X-Range gearing (with a 13t difference between the big and small chainrings) to provide rock solid shifting performance; additional benefits of those chainrings are less weight (compared to traditional multi-piece chainring setups), reduced noise, and the gear changes are less dramatic so a rider can more easily maintain a cadence as they are switching between the two chainrings that allows for an easier time going over climbs, down descents, railing around corners, and for blistering acceleration on the flats. Finally, a wide assortment of crank length and gearing options are available to dial the comfort and performance of the bicycle.

Features:

• Sculpted and skeletonized aluminium crank arms concentrate material where it is needed for strength and stiffness, while eliminating unnecessary material for lighter weight and attractive looks
• 29mm diameter aluminium DUB bottom bracket spindle adds durability, reduces weight, improves stiffness, and simplifies installation (bottom bracket cups and bearings are not included)
• One-piece 2x chainring design is stiffer for improved shifting precision and a reduction of noise compared to traditional multi-piece chainrings
• X-Range gearing with a 13t difference between big and small chainring results in faster and more positive shifts between chainrings and makes it easier to maintain the pedalling cadence when shifting
• Multiple chainring combinations and a wide range of crank arm length options are available to optimize the biomechanical fit and gearing of the bicycle
