Innovative 2-in-1 cycling CO2 dispenser and tubeless tyre repair kit simultaneously inflates and seals tubeless tyres. Machined aluminium construction is both lightweight and highly durable. Hardened steel reamer scours hole, inserts plug and inflates tyre for an efficient and rapid repair. CNC-machined twist knob manually controls release of CO2 gas. Aluminium canister holds the five included tyre plugs and safely stores the reamer when not in use. High quality tyre plugs aggressively seal holes that are too large to be sealed by sealant alone (hole size varies from tyre to tyre). Sleek, compact design fits in a pocket or straps to your bike. Two kit options: Two 20-gram CO2 cartridges or no cartridges, and a simple Velcro strap.
