SRAM Force® Crankset
Competition-focused technology for the serious set, where light 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.

Besides serious weight savings, this bottom bracket means narrow Q-factor, more ankle clearance, greater bearing durability and stronger crank construction.
GXP’s Gutter Seal design cuts friction and weight—improving both feel and performance.
A variant of the external GXP bottom bracket, PressFit cuts weight by up to 40 grams and eases installation by allowing you to press the bearing cups into the frame instead of threading them. It requires no change to the crank spindle length and diameter.
- Pressfit 30™
This is a new design led by SRAM. It’s all the best from BB30 and Press-Fit bottom brackets in one captivating package. This bottom bracket is designed for 30mm spindle cranksets. The key difference with PressFit 30 is how the bearings are fitted into the frame. Bearings are housed in nylon cups which will be pressed into the frames bottom bracket shell. PressFit 30 will feature an integrated seal, pre-assembled into the cups, to further prolong bearing life. Frames will need a 46mm inner-diameter bottom bracket shell to accommodate this system. PressFit 30 for road will require a 68mm wide shell while PressFit 30 for MTB will require a 73mm wide shell. Advantages: Huge weight savings, narrow Q-factor, more ankle clearance, greater bearing durability, stiffer/stronger crank construction, simple installation. Allows for larger diameter frame tubes increasing frame stiffness. Drawbacks: Still searching.
