We're not afraid to say it—our Airlock Presta Valve Tubes are the best performing, self-sealing bicycle tubes available. That's because they feature our powerful Airlock sealant that coats the tube for permanent protection against punctures. Not only this, but the sealant is designed to work continuously in order to prevent slow leaks from occurring, so erring complete catastrophe, you won't have to worry about flatting when you're riding over debris. We even addressed the common issue of sealant pooling with a completely homogenous design, so the tire/tube combo will always roll smooth and even.
Airlock inner tube sealant for the best chance of reducing punctures.
Non-toxic, non-separating formula.
Works continuously to prevent slow leaks.
Homogenous design prevents puddles with no need to shake.

Literally EPIC
Fast shipping and perfect frame set as described. It's literally the lightest built MTB I've ever felt. My wife will be smashing on it at this year at the Leadville 100. LFG Thanks guys!

Exceptional Wheels
The CLX III are exceptional I was a little apprehensive about buying them having ridden the Enve 4.5 but you feel less crosswinds and their lighter and spin fast. The spokes seemed to offer a lot of dampening vibration. Win win in my book.
Heard a lot of good things about this tires put them on my commuter. The roll much faster than the schwable energizers on it. Puncture protection only time will tell.
Great way to charge both the bike and range extender/extra battery at the same time reducing charging time and charging each one by one. Very convenient and useful.
