I recently acquired a 1980s(?) Raleigh Equipe and I am in progress of stripping it down to the bare frame to use it as a single speed commuter, I have got as far to take all the components off the frame except one side of the bottom bracket.
It appears to be a lockring, part of the cotterless bottom bracket if i'm correct?
Which tool do I need to unscrew this from the BB shell? I have tried adjustable pliers but I don't have any big enough, but is it as simple to use a bigger pair? Also I have looked around and seen a "box end tool" maybe that is what I need.
Thanks for your patience, hope someone can help me through building this bike.
