The durability of the multi-sealed high-end industrial bearings from the manufacturer from Portland / Oregon (USA) has meanwhile become legendary. CHRIS KING ThreadFit 30 bottom brackets are designed and built to be long-lasting, low-maintenance and quiet. They form a precise and functional interface between the frame, bottom bracket housing and your crank and ensure easy and trouble-free running.
As with all CHRIS KING components, everything starts with the ThreadFit 30 bottom bracket. These are produced directly by CHRIS KING and, thanks to a special manufacturing process, contain more balls than the competition, which results in a more stable system overall. Each bearing is checked by hand for any quality defects before installation and, if necessary, sorted out. The ceramic bearings installed here are the highest level of evolution. Their smooth running is phenomenal and their durability is unmatched. They also save a bit of weight.
Another plus is the legendary sealing system. It enables easy cleaning and greasing of the bearings with the help of the CHRIS KING Grease Injector. The ThreadFit 30 bottom brackets are suitable for 68 and 73 mm BSA bottom bracket housings, whereby the adaptation to a large number of road and mountain bike cranks with a 28.99 mm or 30 mm shaft is implemented using specific adapter kits.
Chris King has confidence in his products. They show this by giving a lifetime guarantee on their bottom bracket. All you have to do is register them on their website after purchasing.
