The price is good and the product has been utterly reliable. A basic stand would be useful, though the bottle is so light, I am not sure whether it would make a lot of difference.įor myself, I am prepared to put up with the minor inconvenience of a mobile bottle. When you inflate it, it rolls about all over the floor. The only issue I have is that the bottle lacks any sort of stand. The latter usually need a bit of extra help to get them to riding pressure though. Smaller tyres such as 700x42c are a breeze, and I have not really had any issues with 29×2.4 either. It is rare that I have had to resort to more than one fill before I hear the reassuring crack and ping of beads seating in the rim. It’s physics after all! The pressure limit is 160psi, which gives you a lot of oompf!ĭifferent valve configurations regulate the air flow for larger or more difficult tyres. As pressures increase, you have to put in more effort but that is to be expected. Simply close the release valve, attach your pump to the Presta valve and away you go. Or maybe not, particularly when a “low tech” alternative can provide the ideal solution.Įnter the Airshot, a modified, compressed air cylinder which you inflate with a track pump. Why are the best ideas so often the simplest?Ĭan’t get your tubeless tyres to seat with a track pump? You will probably need a compressor. More info : airshotltd.The Airshot tyre inflator. Valve Compatibility: Presta Schroeder adapter available Airshot Tubeless Compressor / Canister Specifications We have some tricky tubeless conversions in the works, so stay tuned for our impressions of how the Airshot works seating tubeless tires.Īndrew Yee and Zachary Schuster contributed to this report. The Airshot system is available directly from the company in the U.K. The Airshot LTD tubeless compressor / canister comes with the fine print on the canister, so you won’t forget the dangers and risks of the task ahead. The company also offers an inexpensive sleeve the help protect it against damage. It comes with a Presta valve attachment on the hose, but a Schraeder adapter is available for a small cost. Airshot claims it has tested the system up to pressures of 160 psi. The 1.15L Airshot canister is 14″ tall and 2.8″ in diameter and weighs 441 grams, making it lighter and more portable than a traditional tubeless pump. Airshot LTD tubeless compressor / canister. Once you fill the canister and attach the hose to your tire valve, you just flip this blue switch the unleash the blast of air. The user charges the Airshot canister with a traditional floor pump via a Presta valve, attaches the hose to the tubeless tire valve and then releases the air to seat the tubeless tire. We’re worried about losing this little piece, but a Ziploc bag and rubber band will hopefully keep everything together. The black hose head threads directly onto a Presta valve with its core in place. The Airshot LTD tubeless compressor / canister comes with an adaptor to attach to Presta valves with their cores removed for a stronger blast. The tube is much shorter than the four-foot tube on the Blackburn, but remembering back to our fluid dynamics days, shorter is better for quick air delivery. The Airshot system is a small canister attached to a short 50cm tube with a Presta-compatible valve that also has an attachment for use with the valve core removed. The Airshot LTD tubeless compressor / canister retails for $59.96 in the US, weighs just 441 grams and can turn any floor pump into a tubeless compressor charging pump. The Airshot canister, produced by U.K-based Airshot, is a new tubeless inflation method that is similar to the compressed air canisters on charging floor pumps such as those from Blackburn, Topeak and Crank Brothers. After the introduction of the Airshot, Specialized also began offering a similar Air Tool Blast Tubeless Tire Setter. Newer charging pumps with canisters, such as the Blackburn Chamber Tubeless Pump, Topeak JoeBlow Booster and Crankbrothers Klic, are portable systems that take a lot of the mystery out of tubeless tire inflation. CO2 cartridges are also an option, but they are wasteful and sometimes not agreeable with sealant. Tubeless riders once had to find an air compressor or hope their floor pump could deliver enough force to seat the tire bead. Tubeless inflation technology has developed over the years. Although setting tires up tubeless is literally a snap, the process still takes a tool to quickly deliver air to the tire to get it into place. While many cyclocross riders are still divided between tubulars, tubeless and tubes, tubeless has won out to meet the demands of gravel adventures.
