just saw that Chris King came out with their new T47 bottom brackets. i'm wondering if i replace my THM PF30 BB with the Chris King T47 w/ ceramic bearings...would it work okay?

seems that it works with a 68mm width.

No, It won't work. The T47 requires a threaded bottom bracket

AlphaDog is right - you need the oversized threaded shell and then you choose the right type of BB to suit your cranks (24mm, 30mm etc).

If you want a thread together PF30 adaptor you'll need something like the ones Praxis do.
I'm left handed, if that matters.

The only BB's that I know work with THM cranks outside of THM, are the C-Bear ones and they use buttery smooth Ceramic bearings. I think Kogel makes a BB compatible with THM as well..

I've never been blown away by Chris Kings BB's though, TBH. More of a culture thing than choosing the best product.
