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.
Did a 90 mile ride on a hot humid day and these bottles kept my electrolyte and carb drink cold long after my insulated podium bottles would have. Also, appreciate that I'm not worrying about the plastic leaching into my drinks on hot summer days. Couple caveats that made me lower to 4 stars. I needed new water bottle cages because one of the bottles popped out of the carbon cages over rough roads which are plentiful in New Jersey. Fortunatly the cheaper recycled cages worked well and I'm not worried about them popping out anymore. One of the stone colored bottles, which looked great when I got them, was scratched up pretty good when it came out on a ride and both are getting a little scratched up in the cages. Still look decent, but you're probably better getting the stainless steal. Overall, the fact that my drinks stay cold made them worth the buy.
I bought the stainless steel Bivo bottles for several reasons: I needed to replace my plastic bottles as they didn't keep my water cold, I didn't want to create more plastic waste going forward, and they had a nice grippy and chip free coating (not sure if the coating is petrochemical free). I used my points to reduce the cost, making the cost competitive with plastic bottles. I'm old enough to have experienced life with little or no plastic and we can do it again. This is a step in that direction (fyi - my bikes are aluminum).
