Single-ring drivetrains simplified the cockpit, but they also simplified the crankset. The Force 1 AXS DUB crankset from SRAM strips away the inner ring, spider complications, and front derailleur cable routing that 2x systems demand. What remains is a direct-mount interface where one chainring bolts to a hollow carbon arm, and the DUB spindle slots into whatever bottom bracket shell your frame uses.

The carbon arms use a hollow construction that SRAM developed for their Red crankset, bringing that weight savings down to the Force tier. Chainring options range from 38T to 46T in 2-tooth increments, letting you dial in the gear range for your riding terrain and cassette choice. The direct-mount interface means swapping rings takes an 8mm hex wrench and about three minutes—no fussing with spider bolts or chainring bolt tools.

DUB addresses the bottom bracket compatibility question that used to require spreadsheets and forum deep-dives. The 28.99mm spindle diameter works with DUB-specific bottom brackets for BSA threaded, PF30, BB30, PF86, and T47 shells. You buy the crankset once and match the bottom bracket to your frame, rather than hunting for a crankset that fits your specific shell standard.... Read More
