The Chris King ThreadFit 30 Bottom Bracket elevates your ride experience to a whole new realm. It’s not only phenomenally durable but fully-serviceable and, crucially, silent. If you value longevity and a smooth ride, day in, day out, then this is an indispensable upgrade to your bike.
Bred from over 30 years of bearing development, the ThreadFit Bottom Bracket has been explicitly constructed as the best possible housing for your cranks. In line with Chris King’s guiding ethos, the ThreadFit is built to outlast your material use of it. Rest assured that, with a 5-year warranty and tolerances usually only employed in aerospace components, this is a truly unrivalled bottom bracket.
The meticulous care and attention invested into the production of each and every ThreadFit engineered, manufactured and assembled in-house at Chris King’s HQ in Portland, Oregon reflects Chris King’s lasting commitment to quality and environmentally conscious manufacturing. Bike disciplines, trends and fashions change but you’ll never go amiss with a ThreadFit Bottom Bracket.
Chris King’s legendary steel bearings and heat-treated, surgical-grade steel races not only form a perfectly integrated system but actually become smoother as they burnish with use – wearing in, rather than wearing out. In contrast to many other manufacturers, Chris King has complete control over every aspect of production, meaning that they can make bearings in-house to a specification that simply wouldn’t be achieved otherwise.
What all of this means for you is less time servicing your bike and more time enjoying riding it, with the added bonus of silky-smooth, soundless movement. Creaky cranks are a thing of the past with the ThreadFit.
Stock size is for a standard 30mm axle and a 68-73mm shell width. We stock a range of conversion kits that allow our ThreadFit 30 to be used with a wider selection of road and mountain
Chris King bottom brackets utilize Fit Kits to ensure that cranks mate perfectly with Chris King's precision bearings, extend product life and reduce the potential for noise. Fit Kits will also allow you to use one bottom bracket with a wide array of cranks, if you happen to change your cranks in the future
