Another piece in the equation that I am not clear on. When the dropouts do not have a way to locate how far back the rear wheel axle should be I tend to go all the way back. Now I wonder if more forward, as in getting the cogs clover to the upper jockey wheel is the way to go?
If the derailleur has a claw hanger (no RD mount on the drop out), should the rear axle mount tight in the claw hanger? Or, slide forward to locate cogs as close to upper jockey wheel as allowable?
Thanks!
