It always happens at the worst possible time. You're flying down a hill, leaning into a turn, or deep into a secluded trail, and suddenly you hear that dreaded hiss. It's the moment every cyclist dreads: a flat tire.
Whether you're an MTB rider taking on rocky singletrack or a road cyclist covering miles on smooth pavement, flats are just part of the game.
Tubeless setups and sealants have made punctures less common, but they're not a magic solution.
Big cuts, sharp thorns, glass, or even a nasty pinch flat can end a ride in an instant — unless you're prepared.
The key difference between a frustrating mechanical issue and a smooth recovery often comes down to what you carry with you and how fast you can act.
FLATS HAPPEN. BE READY.
Let's be real: no matter how good your gear is or how much you prepare, punctures are bound to happen. The big question isn't if you'll get one, but when and how fast you can get rolling again. That's where the Lezyne Tubeless CO2 Blaster comes in.
This all-in-one tubeless tire kit is a total game-changer. It's got a CO2 inflator and a tire plug tool, and it's made of CNC-machined aluminum that's super compact and lightweight. It'll fit in your pocket or strap to your bike.
Say goodbye to the hassle of dealing with messy sealant, endless pumping, the struggle of removing and seating your tire, and fretting about finding multiple tools to do one job.
The Tubeless CO2 Blaster is perfect for riders who want top-notch performance, speed, and peace of mind—all in one sleek package.
WHAT IS A CO2 INFLATOR?
If you haven't used one, a CO2 inflator is a compact tool that injects compressed carbon dioxide gas into your tire.
It's the fastest way to get air back into a flat tire—far quicker than any mini pump, and way more convenient, especially in unpredictable conditions or competitive settings.
Most CO2 inflators consist of:
-
- A head unit that attaches to the valve (Presta or Schrader)
- A chamber or connector for the CO2 cartridge
- A release mechanism (twist knob or trigger) to control airflow
The Lezyne Tubeless CO2 Blaster takes this a step further by integrating a hardened steel reamer and plug insertion tool directly into the head.
This means you can seal and inflate a puncture in a single motion — which is crucial when you're short on time, pressure, and terrain.
It's a great mix of engineering and practicality, made for riders who need precision and reliability.
CAN YOU USE CO2 INFLATORS WITH TUBELESS TIRES?
Absolutely. In fact, CO2 is one of the best solutions for tubeless tire inflation systems, especially when you need to quickly re-seat the tire bead or seal a larger puncture that your sealant alone can't handle.
The Tubeless CO2 Blaster comes with five industrial strength bicycle tire plugs that aggressively seal holes, and the reamer ensures a clean, secure insertion.
In a few seconds, your tire is holding air again, and you're all set. Plus, since it's made by Lezyne, you can trust that every part is built to last, ride after ride.
WHAT CO2 CARTRIDGES DO I NEED?
This is a common question. Here’s the quick breakdown:
-
- 16g cartridge: good for road bike tires (up to 110 PSI)
- 20g cartridge: great for most MTB tires (up to 30 PSI)
- 25g cartridge: ideal for larger volume tires, fat bikes, or backup inflation
Since pressure needs vary based on rider weight, terrain, and tire width, it's smart to test at home before heading out.
The Lezyne Tubeless CO2 Blaster comes in two versions: one with two 20g cartridges, perfect for MTB riders, and one without cartridges for those who already have their preferred setup.
Both come with a simple Velcro strap for clean, secure mounting. Carrying two cartridges also gives you some peace of mind: one for the flat, and one for the unknown.
DOES CO2 LEAK OUT OVER TIME?
Yes, CO2 molecules are smaller than regular air, so they can seep out of the rubber more quickly. A CO2 inflation is a quick fix to get you home or to the end of your ride.
Once you're back, it's a good idea to deflate and re-inflate with a floor pump to keep your tire pressure in check.
Many experienced riders see CO2 as a last resort, not a long-term solution. But when you're far from the nearest bike shop, you'll be glad to have it in your kit.
ARE CO2 CARTRIDGES SINGLE USE?
They are. Once the seal is punctured and the gas is released, that cartridge is done. That's why riders usually carry a spare.
The Blaster's compact design and included plug storage make it easy to be fully prepared without taking up valuable pack space.
Lezyne's cartridges are clean, safe, and easy to handle — no extra adapters or confusing parts needed. Just twist, seal, inflate, and ride.
USING A CO2 TUBELESS KIT: STEP-BY-STEP
The repair process takes less than a minute if you know what you're doing, and having a familiar, easy-to-use tool like the Lezyne CO2 Tubeless Blaster speeds it up even more.
-
- Find the puncture and remove any debris
- Scour the hole with the reamer
- Insert the plug into the reamer on the Blaster head
- Thread the cartridge onto the inflator (if not pre-installed)
- Insert plug into puncture
- Slowly release CO2 using the twist knob to control the airflow

COMMON MISTAKES WITH CO2 INFLATORS
Even experienced riders mess this up sometimes. Watch out for these common mistakes:
- Releasing too much CO2 too fast, which can pop the tire off the rim
- Not seating the plug deep enough
- Touching the cartridge without gloves—it gets cold
- Forgetting to bring a second cartridge
- Using the wrong size for your tire volume
Avoiding these issues comes down to practice, good habits, and having quality gear. With the Lezyne Tubeless CO2 Blaster, many of these risks are reduced thanks to its intuitive design and robust build.
It's not just about function—it's about confidence when it matters most.
