Chris King's legendary in-house fabrication makes for a bottom bracket that's smoother and more durable than anything else on the market. They manufacture their own stainless-steel sealed bearings which allows them to place more rolling elements per bearing for a stronger design and exceptional quality. This 24 mm ThreadFit Bottom Bracket fits English threaded frames of various shell widths for the road and mountain and will fit 24 mm spindles and 24-22 mm step-down cranks but may require use of a Chris King Bottom Bracket Conversion Kit depending on your specific setup.

Available in multiple colors. Lifetime warranty (5-year if purchased before January 1, 2019). Claimed weight is 89.06 g.


Bottom Bracket STD: English (BSA)

Quality build, great design

If Chris King makes it, it will be quality. This BB is no exception. I have one on travel, gravel, and mountain bikes. The bearings feel great, and don't get grunged quickly the way low-end bottom brackets do. I like the grease gun adapter for easy maintenance. Also, the crank adapters are very practical for me, since I change between a shimano 24mm crank and a Quark GXP depending on what I'm doing. All I do is change out the plastic adapters, which takes literally 5 seconds, instead of changing the entire BB. I have a high-quality ceramic GXP BB from another manufacturer, but with this Chris King set up, I don't use it anymore.

Best you can buy

Have used Chris King headsets, bottom brackets and hubs on my road bikes, cross bikes and mountain bikes for years - simply because they are true 'fit and forget' products.

GREAT BOTTOM BRACKET - a very solid product

This is a great bottom bracket, but make sure that you get the proper conversion kit for your crankset. You can find out the correct one to get on the Chris King website. The BB is very solid and easy to install. All Chris King products are quality made and will give you many trouble free miles of riding

Chris King makes some of the best products for cycling with in-house made bearings. Never have to worry about them breaking down.
