I had my bike on the stand, adjusting my SRAM Force rear derailleur, and was having trouble getting it to drop down onto the smallest (outer) cog, even after adjusting cable tension for proper shifting across the range of cogs all the way to the large (inner) cog.
Seems like the high (H) set screw must need adjustment. I'm pretty sure that adjustment would be to turn the H set screw counter-clockwise, to move the set screw out. However, at that point I realized the set screw was already out pretty far. I tried unscrewing it even further, but that didn't help.
Any other ideas? Is a bent hanger the most logical culprit? If that's not it, what else might it be?
