The Orbea Terra gravel uses a BB386EVO press fit bottom bracket shell (46 mm bore, 86.5 mm), a 46 mm smooth press-fit bore, 86.5 mm 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.
