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.
