The PRO CO2 / Tool Bracket keeps your emergency kit out of your pockets and off your frame — mounted cleanly under the saddle where it belongs. The aluminum alloy construction keeps weight to a minimum at just 25 grams, while the bracket holds two CO2 canisters and a spare inner tube in a fixed, secure position. Compatible with current PRO saddles as well as older models, it installs without modification to your existing setup. Note that this listing covers the bracket and mounting hardware only — CO2 canisters and inner tube are not included.
