So that’s what those frame mounts are for!
If you have a pair of mounts on your new mountain bike frame, but no room for a water bottle, chances are they’re accessory mounts. These handy bolt-on spots can be used to secure a tool roll (like this one from Wolf Tooth), spare tube, or even a mini frame bag in a space that might otherwise go wasted.
If you answered yes, tell us what you’ve got mounted to your mounts!
