The wide version of the Rival crank has been specially developed for gravel bikes.
Its widened DUB crankshaft and a chain line that has grown by 2.5 millimeters offers enough tire clearance even for 2.1 inch wide tires.
The wide crank with the corresponding DUB bottom bracket (sold seperate) is even suitable for use on MTBs.
The single chainring option comes with a direct mount chainring with 40 or 46 teeth. In addition to the weight savings due to the elimination of the front derailleur, a 1-by drivetrain is also less prone to failure and more intuitive to shift compared to a 2-way system. The SRAM X-Sync tooth profile with alternating thick and thin teeth (narrow-wide), tried and tested from the MTB sector, ensures that the chain sits securely on the chainring.
The Rival look is visually appealing with its polished, black aluminum crank arms, which are available in lengths from 160 to 175 millimeters. With the corresponding DUB bottom bracket(sold seperate), the crankset is compatible with all common bottom bracket housings. With the SRAM Quarq AXS power meter kit available seperately, this crank can be upgraded to a power measurement system.
Can be paired with either the SRAM AXS Rear Mech, or a SRAM AXS Eagle Rear Mech.
