This easy to mount and easy to use bottle cage affixes to 7/8" tubing, the size of most handlebars and all of our SeatSide Mount Mounting Bars. We don't make this item; it's a good quality system that we were able to find after a fair bit of searching and testing. The clamp size is natively 7/8" (22.2mm), so it doesn't need shims to clamp to handlebar sized things and to our Seatside Mounts and Handlebar Accessory Mounts. Turns out a Seatside Mount can be a handy place to stash another water bottle!
Outstanding! Price was $10 and it included the water bottle cage. Was not expecting that. Bonus! Mounted mine to my side seat hardware next to my side bag. Easy access to hydration. Well made product.
Nice, I would use TerraCycle again for my needs.
