The PF30 standard is widely used. To make it compatible with Shimano and other 24mm diameter thru-axle cranks, as well as improve the system, select this bottom bracket.
The package comes with two cups and CeramicSpeed Bearings installed. There are two options. Both Standard and Coated Bearings feature super smooth CeramicSpeed Balls and hardened-steel races. The CeramicSpeed Coated Bearings have an additional feature: a 3-micron thick metallic layer over the races. This addition makes the races smoother and harder, lowering drag and increasing life.
In The Box
- 1 bottom bracket with bearings installed.
- 2 dust covers.
- All Round Grease.
- Sticker sheet.
The cups have extended sleeves and join with a center section, reducing the likelihood of creaking and increasing the reliability of the system.
The CeramicSpeed Standard Bearings have only 0.3-.04 watts of frictional drag per set, an average drag reduction of 75% compared to stock bottom brackets. This is the result of great design including hardened-steel races, and CeramicSpeed Balls that are 100% smoother and 15% harder than the ceramic competition. They also last longer.
The CeramicSpeed Coated Bearings last even longer and feature even lower drag. Life increases by 60% and drag drops by 50% compared to our CeramicSpeed Standard Bearings.
All Round Grease is installed in the bearings. It can be replaced 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.
