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.

S Works Prevail 3 Fits Like a Glove
The S-Works Prevail 3 is one of the most comfortable bike helmets I’ve worn. The fit system adjusts perfectly, and once I ratchet the MIPS cradle to my head, the helmet almost disappears — it conforms so well that I barely notice I’m wearing it.
Ventilation is excellent. Riding in moderate weather around the mid-70s, my head stayed cool and comfortable without overheating. The airflow design really works.
Thankfully, I haven’t had to test the helmet in a crash, and I hope I never do. But the build quality and design give me a lot of confidence in the protection it offers. Highly recommended.
I feel like I bought a used bike with all of the things I discovered when I got it.
One of the SRAM AXS batteries was DOA and Sierra made it painful to get it replaced, so I just bought a new one on my nickel. I had to trash the tires that had dried sealant in them and I couldn't completely clean it out. It should have come with tubes but was converted to tubeless which I wasn't expecting. I paid a mechanic to go thru the build and he found lots of things not right in the assembly of the bike. It is all good now but I did incur additional cost to make it good.
