Press-fit BB30 crankset compatible with Ultegra 6700

I'm building a cross bike on a 2013 Ridley X-night frame. From the frame's manual:

"The bottom bracket is designed for press fit BB30 cups with a diameter of 46 mm and width of 68 mm. We recommend
to only use plastic press fit cups for our frames. The use of metal cups can damage the frame."

I'd like to use Ultegra 6700 components and a crankset that is PF30 native. What options do I have in crankset that are cross specific, 36/46T?

Thank you!

Got a Proper shop to help you with this job? what kind of tools you got. ?

you can adapt from the press fit to a threaded external bearing with the right adapter .

More QBP stuff.. Ridley frames ship thru them too, now.

Haha, no doubt. What ISN'T QBP now?

Just checking out Whisky Parts new 15mm thru axle fork. "100% Real. 0% Bull." It's just a marketing company. It's all slick.

Everyone go get your 15mm thru hubs!!! Wait, now let's do 20mm!!! 24mm?!?!?!?!?!?

There are two frame standards for a 30mm spindle, PF30 and BB30.

The crank doesn't know or care what kind of 30mm BB you have, it will fit in either. So a crank marketed as a PF30 or BB30 crank should just say "30."

Thanks!
Are there any drawbacks to using adapters and a Shimano crankset like CX70?

I've heard of some creaking with the inserts but I have heard of it myself. I have a BB30 crank sitting in my parts bin if you are interested. FSA SLK-Light ( 130 BCD and 172.5 I think). PM me if you are interested.
