BB86 Bottom Bracket for Shimano

Shimano cranks fit into BB86 frames when you have this CeramicSpeed Bottom Bracket installed. The kit consists of two cups that are pressed into either side of the central opening.

The cups come with CeramicSpeed Bearings installed. There are two versions. The first is our low drag, long life Standard Bearing, with hardened-steel races and our super round CeramicSpeed Balls. The second version is our coated bearing, which uses those same CeramicSpeed Balls installed on coated, hardened-steel races for longer life and less bearing drag.

In The Box

• 2 bottom bracket cups with bearings installed.
• 2 dust covers with integrated spacers installed.
• Spacer tube.
• All Round Grease.
• Sticker sheet.

Technical Data

This CeramicSpeed BB86 Bottom Bracket works with cranks that have 24mm thru-axle spindles, including both Shimano and FSA.

CeramicSpeed standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That represents an average 75% drag reduction compared to standard bottom brackets. The hardened-steel races feature the CeramicSpeed Balls that are 100% smoother and 15% harder than the ceramic competition. The CeramicSpeed Bearings last at least three times longer than other bearings.

Coated Bearings drop friction further and increase lifespan. The coated races see a 50% drag reduction and an improvement in bearing life of 60%.

Changing the grease can tune performance. All Round Grease comes installed, but can be changed for lower drag Race Day Grease, or higher durability Long Life Grease, which adds a bit of drag but stays in when riding through messy conditions.
