I was rummaging through the old threads and came across this one which I found
interesting becuase on my ride yesterday my boom creeped in a bitbit. I thought
it might be because the chain is too tight and when I shift in to the high gears
it puts too much stress on the boom. My did come with a plastic insert alread in
the boom, it has a lip that fits around the edge of the boom. I also have one of
those grey square thingines and I didn't know what it was for. After reading
this I went down and tried to slip a piece of the plastic thing into the boom
but no luck. If I have to do that I will have to disassemble the front end and
then re-assemble it. Is it worth it or should I try lengthing the chain first
and see what happens?

Thanks, Dom.
