Aprašymas
BBright is the Cervlo bottom bracket standard, found on most of their frames, for 79 mm wide bottom bracket shells. BBright is similar to BB30, but is wider on the non-drive side. In order to fit Shimano and FSA cranks into this oversized shell, this bottom bracket, complete with CeramicSpeed Bearings, needs to be pressed in.

RELATED TECHNICAL INFORMATION:
CeramicSpeed Standard Ceramic Bearings – put more of your energy into forward motion by reducing frictional drag wherever you can. CeramicSpeed Standard Ceramic 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. CeramicSpeed balls are 100% smoother and 15% harder than ceramic competition. The bearings last at least 3x longer than other bearings.
All Round Grease
Designed to suit the maintenance of CeramicSpeed Bearings, the CeramicSpeed All-Round Grease maximizes your bearings lifetime and performance. This type of grease is a low to medium viscosity lubricant and works as the best compromise between friction influence and lifetime. We recommend it for optimal use in dry and sunny weather conditions, where no or very little contamination threatens the bearing. The application covers mostly road riding conditions, however it can be used off-road in the same weather settings, on all types of CeramicSpeed Bearings. When lubricating your bearings, we recommend a fill rate of 60-80%.
Maintenance:
Depending on the riding conditions it is recommended once a year to re-grease your CeramicSpeed Bearings.
If used in very wet or muddy conditions, maintenance might be required more often.
If high pressure washer is used, please do not point jet stream to any of bearings (headset, bottom bracket, wheel hub, full suspension links) as it may wash out the grease.
