It would also work for a triple - but choices of compatible derailleurs are limited. Rear derailleur capacity limits probably mean that a triple can't really be used.

I don't know if that would help your speed shimmy. You may want to give it a try.
The handle post height isn't adjustable on my TR. (Well ... there's a little bit of adjustment in the stem but that'll also affect fore/aft positioning.)
