CeramicSpeed BB30 Bottom Bracket Bearings – Coated

The BB30 bottom bracket allows you to pair 30mm spindle cranks to 42mm inner diameter bottom bracket shells. Cannondale pioneered this standard along with specially-designed cranks and many have found the benefits to them. Road versions have a 68mm width, MTB has 73mm. These are also the bearings you can use to replace bearings in PF30 cups.
Low drag, long life super round CeramicSpeed balls installed on coated, hardened-steel races for longer life and less bearing drag.

BB30 was designed to make the bike lighter: no cups, threading, or redundant metal, plus a lighter, stiffer crank. Thats why the crank spindle is 30mm, which was a big jump up from narrow square-taper spindles.
CeramicSpeed standard bearings typically have frictional drag of 0.3-0.4 watts per set. Thats in the range of a 75% drag reduction compared to standard bottom brackets. Thats thanks to balls that are 100% smoother and 15% harder than the ceramic competition. The bearings last at least three times longer than other bearings.
