The FSA BB-4000 is FSA's go-to threaded bottom bracket for road bikes with a BSA (English) 68 mm shell. It uses external cartridge bearings in CNC-machined cups, joined by a composite centre sleeve with double o-ring seals to keep water and grit out of the bearings.
It is built for FSA cranks with the 19 mm MegaExo spindle, the kind fitted to a lot of FSA Omega and Gossamer road chainsets. When your bottom bracket starts to creak, feel gritty or develop play, swapping in a fresh BB-4000 is usually the fix.
