Just following up re. shimming 35mm (34.9). I think 35mm is a great idea as it allows companies to minimize overall length well maximizing post travel with the additional internal space for dropper guts.
Legacy products and a lack of 35mm post options - particularly at the affordable end - mean there is some lag as companies adopt 35mm ID seat tubes.
Kona for example is moving to 35mm and if you check out the seat post spec on 2017 alloy frames released this year you'll see they ship bikes with 31.6 posts and shims: http://konaworld.com/big_honzo_dl.cfm
KCNC and Cane Creek make 31.6->34.9 shims. USE makes 30.9->34.9 shims. It is not hard to get shims to make other posts work in 35mm.
