Long live the King.

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. Will require use of a Chris King Bottom Bracket Fit Kit.

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

It's King - what else can you say?

Bought to replace another King BB that corroded under a ton of trainer seat. My only surprise was that an adapter was needed for a 24mm spindle. It's been flawless since installation.

Best bottom bracket made
by Robert

For the last four years, I have been using the Chris King bottom bracket on my Mountain Bike for winter training rides of 42 milesride 4-5xweek. The bearings roll very smooth and the grease injection tool makes cleaning and lubrication maintenance fast and effective. I was churning through a new Shimano bottom bracket about once a month, every 800 miles, probably because of all of the road grit during the winter and the inability to quickly and effectively maintain them. With the Chris King bottom bracket and grease injection tool I am cleaning and lubing my bottom bracket every 3rd ride when I clean and lube my chain. That is about once every 120 winter riding miles. Very nice system. Like it so much that when Chris King announced early this year they will begin offering a lifetime guarantee on their products I purchased a new Chris King Bottom Bracket that I plan to install immediately. What a terrific Company!

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
by ajlacombe

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

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.

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