I'm about to set up a new bike with the AU 100mm stem and hydration but not the rest of the bar setup (using a Vision trimax Carbon I had from another bike). The tricky part is due to geometry and the current relatively un-aggressive rider position, I need to add ~90mm of stack somewhere. I was thinking 30mm under the stem and 60mm under the pads. I just read through this entire thread and saw that someone basically asked about this exact configuration and you seemed to say that extending the headtube on wider head-tube bikes would probably be the safe bet. I figure 60mm under the pads would also give room for some airflow (though does the straw ruin that). This is going on a Medium Ceepo Viper-R, so pretty standard setup. The head-tube does honestly seem significantly more rounded and wide than say my p3c.

Am I safe to assume that my config is still the best bet or has the idea changed at all behind where to position the bottle?
Thanks!
