Review on Park Tool BBT 18 Bottom Bracket by Peter Alradwan

My peloton started to rattle and it got worse. Peloton support told me the cranks needed to be aligned. The problem, however, was clearly that the bottom bracket was loose. The alignment mark on the mount no longer matched and the carriage could be rotated manually. Using the Park Tool BBT-18 and CCP-44C I was able to reinstall the bottom bracket and eliminate the rattle. I ended up having to do it a second time with a screw lock, but now it's not a problem. As others have noted, the BBT-18 requires a 36mm octagon head.
