Product Description The - For 1x drivetrains on gravel bikes The SRAM Rival 1 crankset is designed for 1x12-speed drivetrains with DUB bottom bracket and is perfect for gravel use thanks to its wide chainline. " Wide" means that the crank produces a larger chainline of 47.5 mm. Combined with an electronic AXS Wide front derailleur, you get more clearance for wider tyres. The X-Sync™ chainrings are mounted via Direct Mount. Gear changes are quick and smooth. If you wish, you can upgrade the crankset with the Rival DUB Wide Powermeter Upgrade Kit at a later date.

It is the system approach through the integration of chainring, crank, shaft and bottom bracket that is decisive for better drivetrain performance. X-Sync™: The X-Sync tooth design is characterised by long, rounded and slanted tooth edges with a narrow profile. Derailleur pulleys with X-Sync technology support the chain guide and remain unaffected by dust and mud.
