Competition-focused technology for the serious set, wherelight weight, strength, and durability come together. The Sram Force crankset is offered in a BB30 option and, just like Sram Red, the BB30 crankset is 10% stiffer, 20% lighter, and gives 300% more ankle clearance than the GXP version. Thanks to the unidirectional carbon structure, both GXP and BB30 crankset versions deliver a sleeker and race-proven design.
  • The integrated carbon-spider construction is light and stiff for greater power transfer with less effort.
  • PowerGlide chainrings are competition proven with long-lasting finishes.
