CHRIS KING bottom bracket ThreadFit T47 30X ceramic | 2021
The durability of the multi-sealed high-end industrial bearings from the manufacturer from Portland / Oregon (USA) has meanwhile become legendary. CHRIS KING ThreadFit T47 30X 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 T47 30X 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 T47 30X bottom brackets are suitable for 68 to 73 mm T47 bottom bracket housings, whereby the adaptation to a large number of road and mountain bike cranks with 28.99 mm or 30 mm shaft is realized via 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.
