I just picked up an older used frame that I like, and it fits me, and... threaded BB shell. It came with some serviceable 105 on it, and I can ride that for a while with no problem. But I have a nice SRAM Red group that I'd love to use if I can. But it's got a BB30 crankset. I searched about but this voodoo is confusing me. I thought about buying a SRAM Red GXP crankset, but it seems they're all 22 speed now.

I'm wondering, ..Is there a good adaptor technology? -- or should I avoid that path at all costs?

Thanks!

What, no used ones or even new-old stock on ebay? Hard to believe.

Voila, like I said: https://www.ebay.com/sch/i.html?_odkw...-BB30&_sacat=0

You can adapt your BSA shell to the 30 mm diameter of the crank, but the spindle is too short. The adapters are threaded cups that sit outboard of the shell and make the width 86 mm wide. Just like GXP but bigger around. If your spindle is only 68 mm, that won't work. I don't think you can do it.

I ride a set up like that, but with a FSA K-Force light BB386 EVO crank and BB on my threaded BSA frames. Bigger diameter and longer spindle.
