Chris King ThreadFit 30mm Bottom Bracket

This product has been deactivated


The Chris King ThreadFit 30mm Bottom Bracket is designed and built to be durable, serviceable, smooth, and silent. Manufactured to create a precise and functional interface between your frames' bottom bracket shell and your 30mm cranks, the Chris King ThreadFit 30mm bottom bracket ensures that your cranks will spin lightly and without interference. To help with bike fit issues Chris King has developed a range of conversion kits that allow their ThreadFit 30 to be used with a wide selection of road and mountain bike cranks. Chris King makes their bearings in-house and their process allows them to place more balls per bearing than their competitors. More rolling elements per bearing translate to a stronger overall bearing system. A bottom bracket-specific upgrade to Chris King's legendary sealing system allows the bearings to be purged and re-greased using their precision made injector tool. This combination of strength and serviceability gives Chris King the confidence to offer an industry-leading 5-year warranty on their bottom brackets. Engineered, manufactured and assembled in Portland, Oregon USA. Requires a Chris King Conversion Kit for installation.
