In November of 2014, Chris King switched from their Threaded Road and Mountain bottom brackets to their ThreadFit24 bottom bracket standard. This move eliminated the need for separate road and mountain threaded bottom brackets. Chris King's ThreadFit 24 system uses a simple selection of conversion kits to bring a wide variety of crank and bicycle frame compatibility to the ThreadFit 24 bottom bracket.

Chris King ThreadFit 24 fits 24mm and 24/22mm spindle cranks like those offered by Shimano, Rotor, SRAM, Race Face, and FSA.

ThreadFit 24 bottom brackets are designed and built to be durable, serviceable, and silent. Manufactured to create a precise and functional interface between your frame's bottom bracket shell and your 24mm cranks, The ThreadFit 24 bottom brackets ensure that your cranks will spin lightly and without interference.

The quality of the ThreadFit 24 bottom bracket all starts with the bearings. Chris King make bearings in-house and their process allows more balls per bearing than competitors. More rolling elements per bearing translates to a stronger overall bearing system. A bottom bracket-specific upgrade to the legendary sealing system allows the bearings to be purged and re-greased using a precision made injector tool. This combination of strength and serviceability gives King the confidence to offer an industry-leading 5-year warranty on bottom brackets.

The design of the bottom bracket means a conversion kit is required. Use Conversion Kit 8 for a 68mm threaded shell and a 24mm crankset. Use Conversion Kit 9 for a 68mm threaded bottom bracket and 24/22mm SRAM GXP road crankset.
