I recently narrowed my aero position on my TT bike which meant my previous hydration bottle wouldn’t fit between my forearms. This bottle enabled me to do that but I’m had to replace the stem and buy a special face plate to accommodate the bottle. I then had to replace my arm rest brackets too. Once fitted the bottle looks great and has a magnetic straw which is really handy. However the bottle does leak so I’ve had to seal the edges when I ride and that fixed the issue. The refill cap is poorly designed and comes loose - I nearly lost it mid ride. If you try and fill up on the fly it also comes apart unless you tape it down too. All in all I’m happy just don’t forget your black electrical tape!
