ThreadFit 30 Bottom Bracket

The ThreadFit™ 30 Bottom Bracket has been designed to fit 30mm and DUB spindle cranks in BSA bottom bracket shells, forming a low drag and reliable interface that will ensure that every bit of power you put in will be exhibited in your pace.

Available in a wide choice of colours, this bottom bracket will exhibit silky smooth action, thanks to its inclusion of Chris King’s own bearings. Made at the brand’s premises, they are renowned for being top quality and easily serviceable, and thanks to their angular-contact design, wearing in rather than out to become faster with age. They make this bottom bracket perfect for competitive racers or those simply looking for the smoothest possible ride.

Choose from either the brand’s uniformly machined, stainless steel bearings with their extraordinarily tight tolerances, or its premium ceramic bearings, which will deliver watt saving and a longer life.

A suitable fit kit will be required to install your chosen crankset.
