Cervlo created their own bb standard, bbright. Found on most of their frames, save the p5, it is asymmetric, has a 79mm width and 42mm diameter. To get campagnolo over-torque cranks to work with the shell, you need this bottom bracket and bearings.
Ceramicspeed standard or coated bearings come installed. Super smooth, super round ceramicspeed balls contained in hardened-steel races are found on both versions. The coated version has a metallic coating laid onto the races, making it even smoother and harder, resulting in lower drag and longer life.
In the box
- 1 bottom bracket with bearings installed.
- 2 dust covers.
- 2 1mm spacers.
- 2 0.5mm spacers.
- 10ml syringe of ceramicspeed all round grease.
- Sticker sheet.
Campy’s over-torque thru-axle spindle is 30mm in diameter, which works great inside the 42mm diameter bottom bracket shell.
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 400% smoother, 128% harder, and 58% lighter than typical steel balls. The bearings last at least three times longer than other bearings.
Coated bearings see another big performance benefit. 60% longer life for these bearings, and a 50% drag reduction.
Changing the grease changes performance. All round grease comes installed, but can be changed for lower drag tt and track grease, or higher durability longlife grease, which adds a bit of drag but stays in when riding through messy conditions.
