Product DescriptionEver since Chris King unveiled their bottom bracket, Shimano riders have reveled in having the King name adorn their drivetrains. This SRAM compatible version allows the Chris King Road Bottom Bracket to be used on all SRAM GXP, Truvativ GXP, and Bontrager GXP cranksets with a stepped 24mm axle. King's bottom bracket was a long time coming, and as expected it upholds the unparalleled quality standard that Chris King established a long time ago with his headsets. The aluminum cups of the Chris King Road Bottom Bracket house 24 stainless steel balls in each of the made-in-house cartridge bearings. They are user serviceable with the Chris King Grease Injection Tool (available separately). 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 durabilityThe Chris King SRAM Road Bottom Bracket is available in Black and Red. This SRAM version does NOT come with cup spacers and is designed to thread directly into a 68mm shell without them.Two final technical notes: (1) The Chris King Bottom Bracket is available in English threading (aka 68mm) ONLY. It is not available for Italian threads. No, there is no way to rig it to work for Italian BB shells. Sorry. (2) It is NOT compatible with mountain cranksets due to one critical issue -- the thickness of the external portion of the cups is different between road and mountain. We offer a very-similar-yet-different Chris King SRAM compatible bottom bracket for mountain bikes. The cups can be installed and removed with a Shimano style bottom bracket tool.
