When the chain rubs on the cage in some gears it is usually a problem of cable tension (or of not trimming the dérailleur properly - or just an extreme combo that should not be used anyway). Sorry, the answer is a bit long (just went back up to write this.)įirst, here is what you did wrong :p (don't worry, we all have been there.) You will do things wrong, but you will figure out how to fix them. Sounds like - but doing your own bike maintenance is a good idea (so: welcome here!).

I'm somewhat befuddled as to what has happened, though I have a strong suspicion I may have redone the cable improperly. I fiddled with it some more and managed toe get it to third, but I noticed that the red markers that show which gear it is in is way to the left, (far past) where it would normally line up with the 3 marker. Additionally the cable feels way too tight when I try to shift up to third. I got it all going smoothly on the lowest (smallest) gear, and re-tightened the nut on the cable, but now when I try to shift to third it won't go. Initially it wasn't moving when I was fiddling with the screws, and in an instructional video they suggested loosening the nut(bolt?) that holds down the shifting cable to allow the derailleur to reset to it's natural position before setting the high/low screws. Recently I noticed that my chain was rubbing on my front derailleur so I went and altered the high/low screws on the derailleur.

I have recently been trying to teach myself more about bike maintenance by doing the work myself (I know horrible idea ).
