overview

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 crankarm 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. compatible with SRAM / Truvativ MTB cranksets only.

Blackbox Ceramic
The ceramic Blackbox sealed cartridge bearings spin more smooth with less pedaling resistance compared to their standard steel counterpart. Additionally the blackbox ceramic technology with its 8 protective seals will endure the elements better than the standard GXP bottom bracket while weighing 10 grams less. The TwoHub Crew highly recommends this superb bottom bracket be utilized in conjunction with a SRAM XX 2x10 drivetrain!
