Granite Punk CO2 Tire Inflator

Hands strapping a spare tube and Granite Punk CO2 inflator to an orange mountain bike frame

Air in. Fingers warm.

A Presta CO2 inflator with a silicone sleeve on the cartridge, so you can meter the air without freezing your hand.

Two Granite Punk CO2 inflators with cartridges placed on a tree stump, ready for quick tire inflation during outdoor rides.

Description

The Granite Punk is a CO2 bike tire inflator for Presta valves, with a silicone sleeve around the cartridge so your fingers never touch the frozen metal. Turn the cartridge to meter the air and stop at the pressure you want.

Choose the sleeve to match your CO2: small for 16 g threaded cartridges, large for 25 g. A plastic ring between the inflator and the cartridge keeps the cartridge sealed while you carry it; take it off and screw the cartridge in to pierce it when you need air. The sleeve has a slot for a Rockband strap, so Punk rides on your frame with your spare tube.

CNC-machined inflator, 24 g with the small sleeve and 25 g with the large. CO2 cartridge not included.

  Feature

  • No frozen fingers The silicone sleeve insulates your hand from the cartridge, which gets very cold as it empties.
  • Air at your pace Unscrew the cartridge to open the flow and screw it back in to slow it, so you can stop at the right pressure.
  • Sealed until you need it A plastic ring stops the cartridge being pierced in your pack. Remove it when you're ready to inflate.
  • Rides on your frame A slot in the sleeve takes a Rockband strap, holding Punk next to your spare tube.
  • Sized to your cartridge The small sleeve fits 16 g threaded cartridges, the large fits 25 g.
