SRAM Force Crankset

Information from: http://www.sram.com/sram/road/products/sram-force-crankset.

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 provides 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.
