Campagnolo Ultra-Torque BB386 Bottom Bracket Cups Campagnolo Ultra-Torque BB386 Bottom Bracket Cups
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.

Shimano Dura Ace BB86 Bottom Bracket Shimano Dura Ace BB86 Bottom Bracket
The 86mm bottom bracket is a relatively new, reasonably beefier BB standard that allows frame designers a little more leeway to play around with seat tube, downtube, and chainstay designs. The new, larger shell requires a larger bracket, obviously, and Shimano designed the Dura-Ace BB86 Bottom Bracket to quite literally fill the gap. While it's a little larger than traditional BBs, the BB86 has the same design as Shimano's other Dura-Ace brackets, with steel cartridge bearings packed inside composite cups and plastic o-rings and dust shields to keep everything running smoothly. The 86 is also compatible with Shimano HollowTech cranks, so you can keep your old crankset even if you're getting a new frame.

Shimano Ultegra SM-BB72-41B PressFit Bottom Bracket Shimano Ultegra SM-BB72-41B PressFit Bottom Bracket
It's easy to overlook the humble bottom bracket in the quest for the most efficient, drag-free riding experience, as this component usually does its job without putting up much of a commotion. Thankfully, though, Shimano knows how integral this component is to your drivetrain, which why it spends considerable time making certain that it uses only the best, silky-smooth bearings, advanced sealing, and high manufacturing tolerances. Such is the case with its new Ultegra SM-BB72-41B PressFit Bottom Bracket design. Where a typical road bike has a 68 or 70mm bottom bracket shell width, a BB86-equipped frame has a shell that measures 86. 5mm wide. A BB86 shell lacks internal threads and has a 41mm inside diameter. This SM-BB72-41B PressFit bottom bracket is made to press right into your frame. It will mate your Shimano HollowTech crankset to any frame equipped with a BB86 bottom bracket shell. This bottom bracket also comes with two steel cartridge bearings that are pressed into composite cups. The cups increase the outside diameter of the assembly to 41mm in order to match the frame's bottom bracket shell. There's a 1. 75mm thick outer-lip that provides a positive stop for the cups when you press them into place. The Shimano Ultegra SM-BB72-41B PressFit Bottom Bracket is available in one size. The assembly weighs in at around 63 grams.
