PF30 bracket to ultegra 8000 crank
PF30 to ultegra 8000,
I’m converting my 2014 Focus Evo from SRAM to ultegra 8000. It is set up as a PF30. EuroBikeParts has the best group set deal I can find. (Feel free to suggest a lest expensive site if you have one). They offer the following options: a BB30 adapter without bearings, a BB30 adapter with bearings, BB 86/92, English, Italian, and “none.” The local bike shop is saying I need a problem solvers bb30 press kit (part
Cr0096). Should I choose one of these options? Or scrap it all and find another solution? Looking to stay in that $50 range.
Thanks!

My Bianchi came with Ultegra cranks, and a threaded nylon press fit adapter for the standard Ultegra bottom bracket. (The Problem Solvers one is also Delrin - nylon)
The threaded Ultegra bottom bracket is aluminum, with very fine threads. It was quite annoying to reinstall the bottom bracket, since it was very hard to know if it was starting to cross-thread. There's some resistance when screwing in the bottom bracket correctly, it's not like metal to metal threads. So the resistance goes up in the first turn or two -- which would also happen with cross threading. (One side was worse than the other, and I wonder if it was damaged by initial cross threading at the factory or bike store when the bike was new.) Other than that, it's worked fine, with no creaking or other problems.

isn't the 30 the bearing ID, and Shimano is 24,so you need to press fit another bearing with a 24mm ID?

Scrap it. Forget about press fit and adapters.
Use an Enduro Torqtite or Praxis. Either installs in about two seconds.

The adapters suck. I recommend the Praxis.

My Allez Sprint is BB30, when I put my Ultegra crankset on it I replaced the BB with a Wheels Mfg. thread together one [THIS ONE]. I've never used one of the adapters, but from everything I've heard, they work but not as well and have a tendency to develop creaking issues.
