When feeling nostalgic I enjoy taking out my mid '70s all campy bike.
Lately, I've been having some shifter problems. Specifically, when
sprinting or climbing out of the saddle, the downtube friction shifter
will allow the rear dereilleur to upshift.
I need advice on how to stop this. One thing it isn't is bottoming out of
the adjusting screw. Now matter how tight I turn the adjuster, the
upshifting will take place. And, of course, this is at the most awkward of
times.
