BB30 Bottom Bracket Bearings
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.
BB30 was designed to make the bike lighter: no cups, threading, or redundant metal, plus a lighter, stiffer crank. That’s 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. That’s in the range of a 75% drag reduction compared to standard bottom brackets. That’s 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.
In The Box: 2 bearings, 2 1mm spacers, 2 0.5mm spacers, 2 dust covers, 30mm wave washer, 10mm syringe of grease, Sticker sheet.
