Which BB30 to Ultra-torque converter?

Hi there, just about to get a Cannondale with BB30. I'd like to use a Campag Ultra-torque chaninset. I've had a look at Ribble and there are 2 sizes. Does anyone know which one I should get?
BB30 68x42
BB30 68x46

You'll also need to loctite them in place, it would be worth reading this long thread for info

To be honest, this looks like a better solution:

Freeborn bikes stock the Shimano version but dont show the campy version on their site yet, might be worth giving them a call http://www.freeborn.co.uk/praxis-works- ... converters
"Yes, we have a Campy version in the works now. It is still in R&D testing but we hope to release it by the end of the year."
Best wishes.

in fact my BB bearings lasted longer with the adaptors than they did after i went back to a bb30 crankset.
This also looks cool, you get new bearing as well, and from the pic, you use the red cones to downsize from 30mm to 24mms. But with alu on alu on steel it would need a lot of grease to stay quiet. http://www.chainreactioncycles.com/toke ... -prod69679
