So it does fit - but the interesting bit that I have noticed is that 10 years ago people erred on the small side if they were between sizes, whereas a lot of the reviews I read these days seem to push towards going a size bigger if you're borderline.
Because seat tube length:reach proportions have changed massively, previously a long front end on a frame meant huge seat tube length so upsizing had implications around being able to put the seat low and all sorts. I went from a medium to large reign but could only accommodate a 100mm droper because my legs are not long enough (this is before the did the big geo rejig on them) but I was faster and more comfortable on the bike everywhere with the longer front even tho I went for a slightly shorter stem at the same time. If I look at a modern Giant Reign, a medium now has a longer front end with a shorter seat tube so I could run full height droppers etc. I think its just been a general realization that the seat tube to top tube length ratios that were common were not ideal.
Agreed ! I have discovered that the new geometry slacker HA 29ers turns plenty fast IF you have the appropriate short stem to match. I found I will fit a L size Giant Fathom XC bike (69 degree head angle) with my normal reach with a 90mm stem, or go to a XL and run a a 60-70mm stem (I'm 188cm tall 34.5" inseam, borderline L/XL), the stability change was great, and the front centre is longer, and could go for a more optimal length stem/handlebar combo, get your balance centered on the bike. Literally the only difference for me between the sizes was 20mm of extra bike in front of me.
