Hi,
I have a Wilier branded FUlcrum carbon 11 speed standard chainset currently on my bike but would like a compact.
I cant afford a Super Record or Record compact so was looking at an FSA set up......however, i cant find any info on the. Campagnolo specific Ultra Torque BB system....
Will other chainsets fit the UT Bottom Bracket set up, or do i need to stick to Campag UT systems?
Alternatively, i suppose its change the BB too?
Any help greatly appreciated.....

The UT chainset/BB uses an axle with a Hirth joint in the middle - interlocking teeth held together by a single Allen screw. There are external bearing cups that screw into a traditional threaded BB shell. It's all one piece with the cranks so you can't fit other chainsets.
So if your bike has a threaded BB shell, you would have to buy, for example, a complete FSA system with cranks, axle and cups. I have no experience with the various press fit BB setups but I assume you would still have to buy a complete new system for those as well to get the compact gears you want.0 -
the UT has 25mm axle - others are 24mm, i swapped mine out for shimano hollowtech 2 as i wanted a variety of chainsets to be compatible between bikesi need more bikes0
