• Longer cage won't allow a bigger range though. I found on a short cage, with 11-34 the chain went loose when on the small chainring and 11T if I left enough chain to be able to get onto big cog and 34T.

  • Of course not, but that's the reason you would need a longer cage. A SS derailleur will probably be fine for any combo as long as you don't go to the extremes of cross-chaining, but I don't know how syncro shift works and it may drop down the front before going through the block etc., so not something I'd risk personally.
