Review on 🚴 Convenient SKS Bottle Cage Adapter Mount for Bicycles - Black Finish by Jathan Louis

I used it to hold my second water bottle on my 100 year journey. I was able to easily mount it to my seat tube and it did the job perfectly. You can adjust the tension very precisely so it doesn't slip but also doesn't squeeze your whistle too much. However, I wouldn't recommend leaving it on the bike all the time - it could eventually damage the paintwork or bend the tube. But for a temporary extra cage keeper, this product worked perfectly.
