For over 35 years, Chris King has probably built the best sealed bearings. This extensive development work also flows into the particularly high-quality ThreadFit 30 bottom bracket and their stainless steel industrial bearings. Designed for cranks with 30mm shafts and frames with traditional BSA thread. Developed and manufactured in Portland, Oregon USA.

It is equipped with sealed steel bearings which are embedded in external bearing shells. Due to a special manufacturing process, Chris King bearings contain more balls than most conventional bottom brackets. This means that the Chris King bottom bracket is ready to take on anything your bike adventures might throw at it. In addition, the specially developed sealing system allows for easy greasing with Chris King bottom bracket adapters for grease guns.

Housing width: 68 / 73 mm

Note on Chris King bottom brackets

To mount a crank with the Chris King bottom bracket, a Chris King Fit Kit conversion kit is also required. These are not part of the delivery and can be purchased in the shop.
