FSA Ceramic Bottom Bracket Assembly - BB86/BB92


Free Shipping on orders over $50*

We've sold ceramic bearing retrofit kits for years and we've always appreciated the fact that FSA has offered ceramic bearings as standard equipment before it was a universal craze. Ceramics offer a measurable reduction in friction. Like improving your aerodynamics, having ceramics makes you faster, but it'll do so with a lot more money left in your pocket.

The FSA BB86 Ceramic Bearing bottom bracket will fit BB86-specific bikes from Scott, Giant, or the ever-growing variety of other frames built with an integrated bottom bracket shell that measures 86.5mm wide x 41mm i.d. The kit comes with two of FSA's sealed ceramic cartridges. Each of the 37mm x 24mm x 7mm bearings are pressed into a forged and CNC machined aluminum sleeve that has a 41mm o.d. and is chamfered to allow an easy start for the press fit into the bike. They have a 1.75mm thick shoulder that sits flush against the frame's bottom bracket shell to provide a positive stop. FSA uses black plastic dust shields to augment the rubber seals built into the cartridge bearing. The shields snap into a small groove machined into the inside diameter of the inner race and run freely with no drag.

The FSA BB86 Ceramic Bearing bottom bracket assembly is all you'll need to mate your crankset to a BB86 specific bike. It comes with the two bearing assemblies and a small syringe loaded with FSA's special ceramic bearing grease formulation. Actual weight is 64 grams.

What do you think about this product?



The title says BB86/BB92 but the description only talks about BB86. Are both sizes available? Or does this somehow fit both?


Is this Ceramic Bottom Bracket 92mm...

Is this Ceramic Bottom Bracket 92mm compatible/recommended for Shimano Saints M825 Cranksets? The options tab only stipulates 1 color / 1 size, but the specific color and size is not mentioned. I'm looking for a BB92 Ceramic option for my Shimano Cranksets. Any help is much appreciated! Cheers
