I should explain 'half knackered' i think. BB threads in the frame were a bit iffy and initially the cup wouldn't screw in square. This sort of knackered the thread on one cup(new Real BB :evil: ). Anyway after much swearing and gentle fettling I managed to get the BB in the frame square. Lovely except as mentioned the axle is too short for any of my current crop of cranks. So now i'm loathed to remove it and will just get some lower profile cranks to suit. It'll probably end up being a single speed so road ones are an option. Thanks for all the info.
