Innovative 2-in-1 cycling CO2 dispenser and tubeless tire repair kit simultaneously inflates and seals tubeless tires. Machined aluminum construction is both lightweight and highly durable. Hardened steel reamer scours hole, inserts a plug, and inflates tire for an efficient and rapid repair. CNC-machined twist knob manually controls the release of CO2 gas. The aluminum canister holds the five included tire plugs and safely stores the reamer when not in use. High-quality tire plugs aggressively seal holes that are too large to be sealed by sealant alone (hole size varies from the tire to tire). 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.
