Profile DesignHSC 250 Top Tube Mounted Flask w/ Cage(Return to Product Page)

I mounted this to my MOG and it fits like the dream, tucks perfectly behind the stem and makes no contact with legs even when out of the saddle. I used it with a gel mix and it works great, but definitely best to be on the lower viscosity end (more water less solid). Holds strong even over gravel terrain. Only notes for consideration are that the bottle itself is $60, no thank you, so if you are doing epics where you sub in bottles that will be a deterrent. Also consider adding a piece of frame protectant where the bottle touches the frame, as it will wear the paint.
