Review on 🚴 Gub Bicycle Bottle Cage Mount: Adjustable Holder for MTB Road Bike Handlebar, Seat Post & More by Robert Tyus

So I used this because I was using a scaffold bag and had nowhere to pour water. I have Jones Loop Bars for more comfort. I tried them with a larger diameter near the stem, but my knees touched the bottle when standing or climbing. I relocated them to the front of the bars using the plastic spacers provided. They don't rotate and stay in place until the bottle is returned to its place. Easy singletrack with some ruts and rocks still ok, I didn't really run the trail cross country at speed to see if they would stay in place, so far very happy with this product as a hydration workaround!
