i'm looking to change my bottom bracket. i currently have an fsa mega exo bb400 and want to upgrade to a hope ceramic. there seems to be 3 options available. 68/73mm, 83mm and a 'road' option.

how do i know which one i need?

Depends on your frame. Also be careful to ensure that the hope BB is compatible with your (presumably fsa) cranks. Not all are the same, and though they are a 24mm spindle, fsa 24 isn't necessarily the same as shimano 24 (seriously). I'd actually ask hope..
