Sram GXP BlackBox Cups with ceramic bearings
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.
Exceed the needs of even the most demanding rider. These ceramic bearings offer a performance advantage over traditional bottom bracket bearings that's almost too great to believe. Besides being 10% lighter than standard bearings, ceramic bearings require an astonishing 78% less energy than the next most efficient BB on the market.
Bearings: Ceramic bearings are more resistant to dirt and moisture and, when properly maintained, will outlast and outperform any other BB on the market. They utilize a lighter-than-normal seal along with stainless steel races and high polish cups and have no equal when it comes to helping you reach terminal velocity more quickly and easily than ever before!
