AAARGHH!!!! Rear derailler adjustment(4 posts)

AAARGHH!!!! Rear derailler adjustmentGDR
Apr 28, 2002 10:09 AM
After a looong time working on my rear derailler I have almost got it adjusted correctly. The bike just will not shift from seven into six (whether the front is in the big or little). When I adjust it so it does shift correctly from 7 to 6 it throws off the rest of the shifting. Please help.

I would start over from scratch. Shift the left shifter into the smallest gear. Loosen the the anchor bolt on the rear derailleur. Make sure the limit screws are set so that the chain can't be shifted into the spokes. Pull the cable tight with pliers and tighten the anchor bole. Usually, if anything, you just have to tension the the cable a little more if the shifting is slow going up to the larger cog. If the bike is old, you may want to inspect the shift cable. Make sure it moves freely. Look under the BB to see if the guide is all loaded with gunk. Good luck and let us know how it goes.

I had a problem much like yours recently. I kept missing gears when I was shifting. It turned out to be the cassette lockring was not quite tight enough. After that the shifting was fine.

Good Luck!!!

This is the URL for the Park Tools Tool School rear derailluer adjustment (say that fast three times!). It's very comprehensive and complete. I would advise you to start your rear der adjustments from the beginning, because each one affects the other. I've taken the Park Tool School at my LBS and it was worth every dollar.
Good luck.
