This Shimano BB71 mountain bike bottom bracket features cups that are made from a fibre reinforced polymer material, which reduces the risk of frame noise and damage. It also comes equipped with sealed cups that keep out dirt and water, making it suitable for all-weather and terrain conditions. Technologies: - Cups are made from fibre reinforced polymer material which reduces the risk of frame noise and damage. - Set includes left- and right-hand cups, 2.5mm spacer, inner cover, and inner O-rings. - Sealed cups keep out dirt and water. - Maintenance-free. - Compatible with 89.5mm (with 2.5mm spacer) and 92mm shells. - 41mm cup diameter. - 24mm inner bearing diameter. - Easy press-fit installation. - Shimano XT.
Water Repellent To make our BB86 Bottom Bracket even more durable, we've used special seals, which keep moisture out while keeping drag to a minimum. A tube is also included to further enhance water repellence. Our bottom brackets are hand-assembled, so we can ensure that all our BBs are finished to perfection to keep your bike riding smoother for longer. Ceramic Bearings With our ceramic bearing option, friction is reduced meaning less energy is required to turn the cranks, they're also more durable, and don’t rust so they'll require less maintenance. If you're a rider seeking out every possible advantage over the competition, the ceramic option can help take your performance to the next level.
A genuine SRAM BB30 bearings kit. BB30-named for its required spindle size-narrows Q-factor, increases ankle clearance, and ups bearing durability. Along with a 30mm spindle, it requires an oversized 68mm or 73mm bottom bracket shell and PressFit bearings held in place by snap rings. Includes two alloy bearings, black caps, silver spacers and washers. Technologies: - 30mm alloy spindle. - Larger bearings for longer life. - 40x30x7 larger bearing size.

This genuine Shimano HollowTech II bottom bracket assembly comes complete with left and right-hand cups, spacers, an inner cover and inner O-rings. The sealed cups keep out dirt and water prolonging the life of this Shimano XT BB-MT800 bottom bracket. Manufacturer's Part Number: BBMT800B
Gutter Seal Technology drastically improves sealing against the elements while reducing seal drag. SRAM also designed a fresh cup forging for a high-end look. The SRAM GXP team bottom bracket sets a new standard in external bearing performance. Technologies: GXP: Giga X Pipe External Bottom Bracket Bearing Assembly. While other systems rely on side loading the bearings to eliminate play, which causes premature bearing wear, the GXP system is different. The GXP system captures the left side bearing between the spindle and the left crank arm while allowing the drive-side bearing to float axially on the spindle, thereby eliminating the necessity to side-load bearings during adjustment. The simplicity of installation is refined: once it is tightened to the proper specifications you are ready to roll with a worry free BB. The GXP system uses two bicycle specific cartridge bearings and eight seals for a smooth and long-lasting ride.

Creak-Free Bottom Bracket The bearings are held in place by an alloy cup, but in order to keep the BB and frame quiet and creak-free, they are housed in a plastic/nylon shell. Finding the right mix of plastic and nylon has allowed us to precisely manufacture these BBs so they won’t deform over time or when they get wet. It also allows the BB to fit in frames that aren’t perfectly aligned. Our bearings inside our BB386 BBs are precisely manufactured to spin smoothly, and when combined with our special seals, repel the elements. The seal is made from a mix of rubber and alloy to provide double protection for the bearings. And, we hand assemble these bottom brackets to ensure none of this development and precision is wasted.

Our bearings are highly polished so they spin smoother for longer, while the seals protect the bearings and races from dirt and debris that try to make their way in.
