The Ridley Fenix (endurance) uses a PF30 press fit bottom bracket shell (46 mm bore press fit), a 46 mm smooth press-fit bore, 68 mm (road) and 73 mm (MTB) wide.
It is a press-fit shell, so bearings or cups press into the 46 mm smooth press-fit bore. Match the shell width as well as the bore, because a shorter unit will not preload the crank across a wider shell.
