So I'm working with the park tool tutorial but I've done it a couple of times in the past. When adjusting my Shimano Deore Front derailleur (height and rotation) it lines up great but when I tighten the mounting bolt the whole thing "banks" inwards and so the cage bottom rises and touches the chain.
- How to i set the height and tighten the mechanism with affecting the other rotation "axis" of the derailleur?
- are there always combination of cogs (front and back) that will cause the chain to run against the cage?.
now some photos. it is very hard to create a stable reference angle with the phone and without a tripod but you will get the idea. This is the chain on the first (small) chainring when the bolt is tighten:
And this is the chain still on the first (small) chainring but now the bolt is almost fully loose, so in fact, nothing changed with the actual position of the mount:
(please ignore the mud.... that's later on the list)
