The Liv Avail (endurance) uses a BB86 press fit (road) bottom bracket shell (41 mm bore, 86.5 mm), a 41 mm smooth press-fit bore, 86.5 mm wide.
It is a press-fit shell, so bearings or cups press into the 41 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.
