My rear der is way out of adjustment... to the point where shifting is pretty much of a crap shoot - will it shift? if so, to what gear/how many cogs will it jump? How long will it stay in that gear? Will it push the chain into the spokes? Into the chainstay?
I've been trying to get it dialed in a bit better. I am making headway, but very slowly. I've read several posts and articles about tuning rear deraileurs, but basically I do the trial and error method. I adjust a limiting screw slightly, the re-evaluate. Needless to say, this is very inefficient, and only moderately effective.
So here are my questions. As I see it, there are 2 main ways to adjust the rear deraileur - the two limiting screws and the "nob thinging" under the rubber boot (like my technical terms? What's that thing called?). I think if I understood what exactly these things did, I could do a better job tuning the der. From what I can see, in my limited experience, the limiting screws adjust how far the chain is pushed every time you shift. The nob thing adjusts the alignment of the pulleys with regard to a specific cog. Is that right, or am I way off the mark? Additionally, when adjusting the limiting screws you can tighten them down or loosen them up. Does tightening them down increase or decrease the "throw" of the chain?
Am I even close? I guess if I understood how these things worked, tuning the rear der would be much easier.
Thanks.
