Ceramicspeed EVO386 Sram GXP Bottom Bracket Cups 86.5 mm Black
EVO386 is a standard developed by Wilier and FSA featuring the shell width of BB86 (86.5mm) and the diameter of a PF30 (46mm).
The extra width allows for more design flexibility and the wider shell allows for bigger bearings.
The kit comes with CeramicSpeed bearings installed in two cups.
Both Standard and Coated Bearings are available.
Both utilize super smooth CeramicSpeed balls and hardened-steel races.
The latter has an additional metallic coating on the races to further smooth and harden the steel, better for increasing life and lowering drag.
