Ceramicspeed EVO386 Shimano Bottom Bracket Cups 86.5 mm Black

The EVO386 standard is designed for large spindles.

The CeramicSpeed kit for Shimano allows you to install Shimano or FSA cranks with 24mm thru-axle spindles.

The cups come with CeramicSpeed bearings installed.

Standard and CeramicSpeed coated bearings are available.

Both use super soft ceramic speed balls and hardened steel tracks.

The latter has an additional metallic coating on the tracks to soften and harden the steel even more, which further increases life and reduces resistance
