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

I got this adapter for my old bike that didn't have pre-drilled bottle cage holes. It fits great although I used some tape to secure it as the 2 plastic extras made the tube too small. It comes with the tools needed for installation and is fairly easy to install, but the bottle cage is more difficult. The only thing I would wish is that the entire length is closer to the ring as this leaves a lot of space between the frame and the bottle cage. I would recommend if you need an extra seatpost mount or want to breathe more life into an old bike.
