I have a set of 9 speed Record Ergo shifters and am having a problem with the right one. When I
upshift it shifts to far. To get the rear derailleur into the correct position all I have to do is
apply a little pressure on the thumb button and the chain is positioned on the cassette correctly.
What could be causing this problem? Do I need to replace a spring or something? I don't think it's a
gunked up cable. If I need to replace parts could someone tell me which parts I need. I think it's
time for me to increase my wrench twisting skills and dive into the guts of this ergo shifter.
Thanks
