We've paired the venerable Chris King SRAM Bottom Bracket with the Chris King Grease Injection Tool in one package that will get you going on the finest bottom bracket known to man and the injector tool will keep it that way -- factory fresh and spinning effortlessly. Ever since Chris King unveiled their bottom bracket, Shimano riders have reveled in having the King name adorn their drivetrain. This SRAM compatible version allows the Chris King Mountain Bottom Bracket to be used on all SRAM GXP, Truvativ GXP, and Bontrager GXP cranksets with a stepped 24mm axle.

The aluminum cups of the Chris King Bottom Bracket house 24 stainless steel balls in each of the made-in-house cartridge bearings. They're user serviceable with the Chris King Grease Injection Tool (included). Simply squirt fresh grease into the bearings to purge the gunky, used grease and keep things spinning smoothly. This system has a fringe benefit for racers -- it gives you the option of running a very thin grease or even oil on race day in order to minimize bearing drag. And when you're not racing, it's a snap to inject thicker grease to maximize durability.

The Chris King SRAM MTN Bottom Bracket w/Injector Tool is available in Black and Red. It's compatible with both 68mm and 73mm bottom bracket shells and comes with two 2.5mm aluminum spacers for use with 68mm shells.

Two final technical notes: (1) This version of the Chris King Bottom Bracket is specific to mountain bike cranksets. It is NOT compatible with road cranksets due to one critical issue -- the thickness of the external portion of the cups are different between road and mountain. We offer a very-similar-yet-different Chris King SRAM compatible bottom bracket for road bikes. (2) This bottom bracket, when installed in a 73mm shell and combined with a GXP crankset is NOT compatible with either E-type front derailleurs or bottom bracket-mounted chainguides. The cups can be installed and removed with a Shimano style bottom bracket tool.

Good Product

  • Familiarity: I've put it through the wringer

After blowing through a SRAM GXP BB every three months or so I decided to drop some cash on the King BB. Though on the surface this product appears expensive, I installed in 1.5 years ago and it still spins like new. The grease injector is easy to use, pull the crank and dust seal, insert the injector and pump in your favorite lube. I expect this BB will last well beyond the 5 year warranty that it come with!
