Never mind the punctures, here’s the new Granite Punk CO2 inflator!
 
It works with 25g CO2 canisters and weighs just 25g so it won’t weigh you down.
When anarchy strikes and your tires go flat, just grab the Punk and you’ll be kicking out the jams again on the trails in no time. 
 
The Punk CO2 Inflator is a tiny but mighty stashable tool that’ll ensure you're never left stranded on the trails.

It works perfectly with MTB carrier straps and allows easy inflation of tires.
