The Topeak JoeBlow Booster is the ultimate solution for mounting stubborn tubeless tires. It combines the technology of an air compressor with the portability of a floor pump. The aluminum cylinder is designed for pressures up to 11 bar and has a volume of 1 liter. With a single charge of air, you can effortlessly fill and properly mount a tubeless tire. To do this, fill the air chamber by pumping in "Charger" mode and place the pump head on the valve. Once you switch to "Inflate" mode, the compressed air flows steadily and quickly into your tire. Afterwards, you can continue in "Inflate" mode, and thanks to the air release button, the tire pressure can be fine-tuned just like with a conventional floor pump. **Top Features:** - Ideal for inflating tubeless tires - 2 modes – "Charge" with compressor function and "Inflate" like a regular floor pump - Stroke volume: 303 cm³ - Capacity: Max 160 psi / 11 bar - Top-mounted 3" pressure gauge - SmartHead™ DX3 pump head with air release button & extra-long hose (152 cm) - Suitable for Presta (SV) and Schrader (AV) valves - Aluminum cylinder with sturdy steel base - Dimensions: 74 x 24 x 18.5 cm **Test Results:** - Mountainbike – Test winner (01/17) - Reddot Award 2016 – Winner **Delivery includes:** - 1 x Topeak JoeBlow Booster floor pump
