The Bottom bracket is a key component to every chainset. Smoothness movement is critical, yet must be balanced by enough sealing technology to sustain a reasonable lifetime of use. FSA MegaExo bottom brackets are the result of years of development, and feature exclusive innovations to guarantee the best balance of efficiency and durability. FSA use the state-of-the-art materials like Silicon Nitride formed ceramic ball bearins, or highly polished chrome steel ball bearings, depending of the level of the bottom bracket.

With their new DUB cranksets and bottom bracket standards, SRAM have upped their game, with the two products combining to create a lighter, stiffer and more durable system. SRAM's DUB Threaded Bottom Bracket fits in your standard threaded bottom shell and provides a stiffer and more durable bottom bracket compared to the competition and SRAM's own GXP design. By using a 28.99mm axle, the DUB bottom bracket offers bigger bearings than bottom brackets used for 30mm crank axles, improving durability and stiffness, as well as being lighter. The DUB system replaces SRAM's previous GXP and BB30 crank and bottom bracket systems to provide improved durability, better compatibility and a stiffer, stronger and lighter product. DUB cranks can be used with any existing bottom bracket standard when used with the appropriate DUB bottom bracket. Performance benefits aside, it also means your crank is future proofed in case you happen to swap your frame. Easy to install and highly durable, SRAM's DUB Threaded Bottom Bracket sets a new standard in durability and longevity.

The SRAM GXP Team bottom bracket is designed for both SRAM mountain bike and road drivetrains, delivering flawless performance at an inexpensive price. The cartridge bearings use gutter seal technology to keep the elements out and the grease in for significantly increased longevity over previous incarnations. SRAM's 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.
