We at SRAM saw the opportunity to make a better press fit system where all the best from BB30 and PressFit bottom brackets would be combined into one captivating package. PressFit 30 will feature an integrated seal, pre-assembled into the cups, to further prolong bearing life. 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. This bottom bracket is designed for 30mm spindle cranksets.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.•Easy installation•PressFit cups for lighter weight•Narrow Q-factor and more ankle clearance•Integrated gutter seal to prolong life•Integrated adjuster•30mm spindle diameter•40x30x7 larger bearing size•Bearings: Ceramic as standard

Gutter Seal Technology drastically improves sealing against the elements while reducing seal drag. We’ve designed a fresh cup forging for a high-end look. A new standard in external bearing performance.GXP’s Gutter Seal design cuts friction and weight—improving both feel and performance.Other systems rely on side-loaded bearings to eliminate play, causing bearing wear. GXP captures the left-side bearing between the spindle and the left crankarm and allows the drive-side bearing to float axially on the spindle. There's no need to side-load bearings during adjustment. No excess wear. And a much simpler installation. Just tighten to the proper specifications and you're ready to roll, worry-free. GXP's two bicycle-specific cartridge bearings and eight seals ensure a smooth, long-lasting ride. Our new Gutter seal system takes a two stage approach in directing contaminates away from the bearings providing longer bearing life. GXP s Gutter Seal design also reduces friction, 35% less drag than the current GXP BB, improving rider feel and performance. Gutter seal system has deeper installation tool grooves which provide stability and support while applying torque to the adapter cups. The design and material choice has dropped 15g out of the GXP BBs.

Compatible with 68mm or 73mm English threaded bottom brackets in frames with 68mm or 73mm PressFit 30 shells.

A variant of the external bottom bracket, PressFit cut weight by up to 40 grams and provide easier installation by allowing you to press the bearing cups into the frame instead of threading them. There's no change to the crank — spindle length and diameter remain the same.
