Our ThreadFit™ 24 bottom brackets are designed and built to be durable, serviceable, and silent. Manufactured to create a precise and functional interface between your frames' bottom bracket shell and your 24mm cranks, our ThreadFIt™ 24 bottom brackets ensure that your cranks will spin lightly and without interference. To help with bike fit issues we have developed a range of conversion kits that allow our ThreadFit™ 24 to be used with a wide selection of road and mountain bike cranks. As with all Chris King components in our ThreadFit™ 24 bottom brackets it all starts with the bearings. We make our bearings in-house and our process allows us to place more balls per bearing than our competitors. More rolling elements per bearing translates to a stronger overall bearing system. A bottom bracket-specific upgrade to our legendary sealing system allows the bearings to be purged and re-greased using our precision made injector tool. This combination of strength and serviceability gives us the confidence to offer an industry-leading 5-year warranty on our bottom brackets. •Engineered, manufactured and assembled in Portland, Oregon USA. •5-year built-to-last warranty. •Easily serviceable with our integrated grease injection system. •Legendary in-house made bearings. •Available ceramic bearing upgrade. •Easily inject your choice of grease for different riding conditions.
