A powerful blast of air is required for tubeless tyre assembly so that the tyre bead quickly presses into the rim flange and the tyre is sealed. “Depending on the combination of tyre and rim, it doesn’t always work with conventional floor pumps,” explains Peter Krischio, Schwalbe Product Manager Race. In the professional workshop or at the garage, a compressor helps out.
For safe and easy fitting without a compressor, Schwalbe is now launching the Tire Booster, which was developed in collaboration with the British start-up Airshot. With it, a pressure of up to eleven bar can be immediately applied in the tyres. “The tyre immediately seats itself safely on the rim and seals everything evenly,” says Peter Krischio. “The Tire Booster is a significant advantage for assembly of tubeless tyres. At a light 435 grams, you can easily take it along on your trips.”
If you need an even bigger flow of air, a special adapter is also available. For this, the valve insert is removed and the adapter is screwed directly onto the valve spindle - the airflow is thus maximised.
And this is how it works: connect the Tire Booster to a conventional floor pump using the SV valve on the Tire Booster, fill the cylinder and then operate the quick-release valve. The air immediately distributes itself evenly and the tire seats itself - usually with the typical loud crack - firmly on the rim.
The Schwalbe Tire Booster will be available from December 2016 from specialist bicycle retailers for 59.90 EUR.
