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.

Note: Sealing performance may vary based on puncture size, tire size, and tire pressure. - Compact tubeless tire repair kit. - Machined aluminum storage tube doubles as a handle. - Combined tire reamer and insertion tool. - Includes five tire plugs. - Includes 2 x 20g CO2 Cartridge and Velcro Strap.
