SRAM Rival 1x D1 DUB Wide 172.5mm 40T Crankset

SRAM 1x
Sometimes simplicity is best. SRAM pioneered the 1x setup and have seen it adopted throughout cyclocross, gravel and time trial disciplines where consistent chain control is crucial and a simple setup is ideal.

SRAM Wide
For those seeking adventure and challenging route, running wider tyres gives you more comfort and grip. To accommodate wider setups SRAM have designed the new Wide DUB system. A longer DUB crank spindle creates a wider stance at the crank arms and chainrings to give extra clearance for those wider tyre setups, so you can go further and explore more.

DUBT
The relationship between bottom bracket spindle and bearing is the core of DUBT technology. It's where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler-and better integrating the relationship between chainring, crank, spindle and bottom bracket. It's this clear system approach that equals better drivetrain performance.
