Hi,
I got a used Shimano 105 group for a song, and everything's working
great except that the SPIDER of the right crankarm is bent, so the
chainrings wobble. I'm definitely sure that the chainrings themselves
aren't bent, have laid them out on a flat table and there's no obvious
problem, but when I put them on the spider and tighten 'em down, it
doesn't lay flat...
Any tips on fixing this? Would bending it back into shape weaken it
too much (it appears to be bent about 2 mm)? I imagine I could bend it
back into shape with a vise, but what part would I want to try bending?
I dunno how to align it properly other than by trial and error, which
could be very tedious...
Thanks,
Dan Lenski
