Yeah, I'm about to fold um...two final questions.
1) Can I use a piece of pvc pipe (the heavy stuff) for a spacer (short term) until the real deal gets here?
2) I routinely adjust my chain and rear derailleur and get very smooth, precise shifting as I start out, but over time 8 - 10 mile mark, shifting gets mushy, and degrades to the dreaded "auto-shift", randomly. I am gravitationally challenged. Pretty severe. Is my weight causing "stuff" to flex back and forth to the extreme that the adjustments are negated. I have a Jamis Coda Elite, a pretty good quality steel frame, but this is getting tiring. Is there a solution, if flexing the frame or flexing something, due to my weight, is messing up my derailleur?
