Product Description The Force 1 D2 DUB DM 1x12-speed crankset by SRAM with carbon - An eye-catcher for road bikes This SRAM Force 1 D2 DUB crankset with carbon arms is recommended for a 1x12-speed drive on your road bike or triathlon bike. But even if you veer off the asphalt paths on a cyclocross or gravel bike, the X-Sync chainring profile ensures strong chain hold. The shiny detail around the logo and series name attracts attention without being too obtrusive. The lightweight, stiff chainring is attached via Direct Mount. Thanks to DUB technology, the crankset is extremely durable and perfectly matched to DUB bottom brackets.

Stiffness meets durability. SRAM has gone a step further and made everything even easier and better. It is mainly the system approach through the integration of chainring, crank, spindle and bottom bracket that means 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.
