Review on Enhance Your Cycling Experience with the SHIMANO Dura-Ace Di2 Seat Tube Bottle Cage Relocator by Brody Jacobs

As others have said, this works great. I have a small S Works Roubaix. With Di2 battery. The placement in the cage is not suitable for a decent sized can (not to mention my big butt). This solves the problem by allowing me to move the cage DOWN (the instructions say it should move up. Just put it upside down). I also agree with beef about lousy ingredients. This is my second unit. The first fell apart after 3 years/18,000 miles.
