Derailleur hitting spokes

krfletcher said:

About a week ago I noticed that the rear derailleur, a
shimano, on my trek hybird started to hit the spokes of
the rear wheel in lower gears. I don't remember anything
happening to it, but I guess something could have knocked
it out of place. I tried adjusting it myself and fiddling
around but nothing I did changed it's position. Does
anybody know how I can adjust it so that I can use the
lower gears again? Thanks.

I strongly suggest you visit your local bike shop and have
this checked. This is not something to fool with.

Possible causes are a bent dropout on your frame or a bent
derailleur.

Try sighting the wheel from behind. The wheel should be
straight, and centered in the frame, and the deraileur cage
should be perfectly vertical. DON"T try pulling on the cage
to straighten it.

If adjusting the "L" screw doesn't suffice, or if it results
in not being able to use your low gear before the derailer
hits the spokes, then your derailer hanger is bent. Replace
the hanger or have it straightened at a _good_ bike shop.

Had this a couple of times - both times worn pivots in the
mech - replacement mech sorted it.

East to spot - take tension out of cable and try wobbling
pivots around - if they wobble then that's it No amount of
adjusting will solve it and you could end up bending a
perfectlt good hanger.

Either the der hanger is bent or the limit screw needs to be
turned in or both. Spend $5 and have a LBS do it, and watch.

Try out the limit screw first - it will take you only a
minute. I had a similar problem and found that even though
my derailleur was bent, I had just enough clearance to
adjust the limit screw to keep using it for a long time. If
that doesn't work, take it to the bike shop.

There is a limit screw, but if the top jockey wheel is in
the correct place, just bend the cage back. I do this by
grabbing the jockey-wheel cage and pulling.....
