Inflating tubeless tires with the milKit Booster is more efficient than any other existing solution as there are no additional hoses or valves. This means the full air pressure goes straight to your valve. The milKit Booster is small and very lightweight, only 150 grams, and therefore can be brought along in the back of the car or on any ride. The option to use the Booster as a water bottle makes it the perfect, 2-in-1 product. A separate bottle cap is included in the booster package. The new 0.75L / 25 oz bottle fits into a bottle cage and is still large enough to be able to inflate even the most stubborn tires, from road up to 29 plus, really well.
