BB30 and Ultegra Cranks
Thinking about upgrading my CAAD-9 cranks to Shimano Ultegra's to match the rest of my now Frankenbike's components. What else will I need to buy, if anything to handle this kind of switch? The CAAD-9 runs a BB30.
Note: Not much beyond a bike tinkerer, so this may be outside my capabilities. Or perhaps not! Unsure entirely.

There are adapters that basically install a threaded interface into the BB30 bearings but they're somewhat prone to creak. I'd recommend getting a single-piece or thread together BB30 to HTII bottom bracket, like https://www.bbinfinite.com/products/...ant=9864658179 or https://wheelsmfg.com/bottom-bracket...ano-black.html . You'll need to be comfortable banging out the old BB bearings and installing the new BB, which in the case of a single piece BB will probably require a BB bearing press, and in the case of a thread together BB the appropriate splined BB tool.
