BBinfinite adds perfectly aligned DUB bottom brackets to silence SRAM’d bikes

As a machinist, I feel there is a better solution. What if you turn, bore, thread and part off an aluminum slug in one setup for perfect alignment. Use a standard thread pitch used on bicycles, and then pot the slug into a carbon frame, or weld it into an aluminum frame.

I would then make aluminum cups that externally hold bearings and seals. Replacement would simply involve unthreading an old cup assembly, and threading in a new cup assembly.

What do you think? Yay? Nay?

BBInfinite are very good. Most situations don’t require them, but when they do, you’ll be glad they’re there. Bonus for the plastic sleeve between bearing and spindle. Every bottom bracket should have that, especially with aluminum spindles.
” (although, granted, it’s greatly diminished with the thread-together options)” -Nope. The threads are a loose fit, and the threaded part of the center sleeve is thin, allowing distortion. The press-fit part is a loose fit, necessary to be able to turn the cups in the threads. I’d go so far as to say that thread-fit bottom brackets are MORE creak prone than standard.

Not sure anyone is still reading these, but this reminds me of how square-taper BBs evolved from the the old style cup-and-cones, where each cup threads into its own side, to one-piece BBs (Shimano UN-55, etc.) where the entire assembly threads into one side and the piece that threads into the opposite side is just a spacer that locates the assembly in the center of the shell but doesn’t thread to it at all. Does anyone else see this as a similar evolution in press-fit?

I can’t see a reason for me to move past threaded shells and Hollowtech BBs. So simple to install and maintain.
