Crankarms without chainrings give you flexibility that complete cranksets don't. The Force D2 DUB Crankarm Assembly ships as a spider-and-arms unit ready for whatever chainring configuration your riding demands. SRAM's direct mount interface accepts their road chainrings in single, double, or wide-range setups, so you're not locked into a ring combination chosen at the factory.

The hollow carbon arms use the same construction as Force AXS complete cranksets. SRAM's DUB spindle system runs through the center, compatible with their DUB bottom brackets across threaded, press-fit, and T47 shell standards. That means one crank arm investment works whether you're building up a BSA-threaded steel frame or a press-fit carbon race bike.

This assembly makes sense in a few scenarios. If you're running a power meter spider, you avoid paying for chainrings you'll immediately remove. If you swap between road doubles and gravel wide-range setups on the same bike, you buy rings separately and change them as needed. If you crashed and bent a chainring but the arms survived, you replace only what broke.... Read More
