I've recently had my Roberts resprayed (see pics), and I have a query that maybe someone might answer: the bottom bracket has only one cable guide, for the rear mech, so how can I feed the cable up for the front mech? The small drill hole in the middle of the BB seems to be a drainage hole, with no thread, so no possibility of screwing in a plastic cable guide I think. Many thanks for some tips here. (I used to live near Roberts and raced on their frames as a 'junior' in the 80s).
