They will do it to any bar and stem combo you want
no, if you want full carbon they will make you stick to enve stem.
what do you mean "how"?
there are 2 screw holes on Pro Stealth Evo underneath, to fit this mount, so if the gap between bolts is the same I could fit one of them garmin mounts.
sorry, didn't know that! Integrated hole in the stem misguided me. Having said that, not sure if the hole spacing is the same...
