CeramicSpeed BB30 Road/MTB Standard BB Bearing Kit Black

Improve Bike Performance With CeramicSpeed
Bike performance improvement can often be attributed to the 'little things' like adding these CeramicSpeed BB30 Standard Bearings into the mix.

Pair 30mm Spindle Cranks To 42mm Inner Diameter Bottom Bracket Shells
The 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. The BB30 bottom bracket allows you to pair 30mm spindle cranks to 42mm inner diameter bottom bracket shells. These are also the bearings you can use to replace bearings in PF30 cups.

Low Drag, Long Life Hardened-Steel Races
When it comes to CeramicSpeed bearings you have two choices. The first choice is this low drag, long life Standard Bearing, with hardened-steel races and super round CeramicSpeed balls. The second choice is the CS Coated Bearing, which uses those same balls installed on coated, hardened-steel races for longer life and less bearing drag. The version provided with this purchase is the Standard (non-coated) option.

Run Super Smooth And Requires Minimal Maintenance
Whatever your cycling discipline Road, TT, Tri, Track, Cross, and MTB you can use CeramicSpeed bearings to capitalize on the benefits of super low friction, better power transfer, and increased bearing life. CeramicSpeed standard bearings typically have a 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. Best of all these bearings last at least three times longer than other bearings, run super smooth, and require minimal maintenance.
