You've invested in the groupset of your dreams, and at its heart is that beautiful Campagnolo Ultra-Torque crankset. The impeccable power transfer, the classic logo, the stately look of the raw carbon finish -- just looking at it is almost as much fun as turning it over. So why would you trust it to anything other than Campagnolo's own Ultra-Torque BB386 Bottom Bracket Cups? After all, like the doomed Italian lovers Paolo and Francesca, the two were made to be together. Don't keep them apart. The Campagnolo Ultra-Torque BB386 Bottom Bracket Cups are made to mate exclusively with Campagnolo Ultra-Torque cranksets. They aren't compatible with Campagnolo Power-Torque cranksets.
