In the stand today we have a 2021 specialized tarmac SL7. Service riding has called for a bottom bracket. Usually this is going to be excessive play or just simply worn out. The bearings are going to be really rough. This one's really easy because it's a BSA bottom bracket. That means that this one actually just has a threaded interface here that gets the bearings into the frame. Another common one that you'll see the industry is kind of moving away from it. At the moment is the press fit bottom bracket. It was a lot easier to achieve for the manufacturer. Carbon frames especially without having to worry about cutting threads into any of the shells. So between that and a little bit of a weight consideration of the industry move toward that. But they are little finicky. They can be creek prone and the industry is largely moving back toward threaded bottom brackets.
