Currently, I am working on an article towards diagnosing different problems I have encountered with bottom brackets in multiple frame materials and the resulting solutions. It’s a rather decent size article, hence the precursor and delay in publishing. I expect to have it up later this evening and am looking forward to comments and questions. Many times, the bottom bracket area is viewed with high caution or mystery, when most of the time (except special new tech) is boils down to a couple of maintenance issues or replacement. The in-between parts are the fuzzy math I’ll try to clarify.
