Been doing repairs for US colleagues here in Morocco.

Have a colleague with an old Nishiki Manitoba with triple Biopace cranks. His bottom bracket needs overhauled or replaced. He is leaning towards replacing with a cartridge type.

So I do not have to tear his bottom bracket apart to measure the spindle andkn so he can keep riding...does anyone know what spindle length he needs?

I am thinking it is a 121mm spindle for a biopace triple...anyone know for sure?
