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.
