Thanks for the replies and advice.
I dont think I can press it out as such as there is a locating lip in the middle of the rocker which would prevent it being pushed out from the other side. I cant get behind the race at all which is the main problem.
mtbdave and gtRTSdh, if you have a spare that would be great, if you could PM me when available and we can sort something out.
gtRTSdh - Yeah, The lugs were cracked on the BB when I got the frame. I've since had it re-welded and it seems to be holding up OK.
Cheers
