Introducing a compact and clever solution for filing tubeless tires without an air compressor.

MilKit Booster Makes Tubeless Tire Installation Easy and Affordable

Two years ago milKit, a young Swiss cycling brand, introduced a valve system that simplifies the handling and maintenance of tubeless tires. Vital MTB previously reported on it here. For their next product innovation, milKit have created the Booster, which eliminates the need for an air compressor when seating tubeless tires.

"Many tubeless users and bike mechanics approached us and said that they loved the milKit valve system, and asked if we couldn't also find an easy solution to the one problem remaining with tubeless tires: inflating them without having to use a compressor," says Pius Kobler, co-founder and CTO at milKit. "This inspired us to develop the Booster.”

Inflate the booster with your bike pump, remove the valve core from your tubeless valves, push the booster on the valve stem. It’s that simple.

To solve the question of how to compress and deliver air to a tubeless tire using commonly available materials and fittings, milKit’s designers looked to standard aluminum drinking bottles, which are ideal pressure-storing devices that are also lightweight, robust and inexpensive. Combined with well-designed valve and fitting designs, the aluminum bottle makes the basis of the Booster system, which works as simply as this: Inflate the booster with your bike pump, remove the valve core from your tubeless valves, push the booster on the valve stem. It’s that simple.


There are no hoses or additional valves to reduce air flow, making inflating tubeless tires with the milKit booster more efficient than with any known existing solution. The milKit booster is very lightweight and therefore an ideal companion to bring along on the ride – and with the included line and bite valve you can turn the booster into a handy drinking system.

This simple solution is now available at Kickstarter for early backers and has already been successfully funded.

    Great idea. I'd also be stoked to see a small reusable cartridge to replace the disposable CO2 cartridges.

    You can use the milKit booster as a CO2 cartridge replacement. You can inflate it at home and carry it with you - ready to boost.

    The booster with the bottle weighs only 5 ounces.

    I am currently running the milkit valves in my wheelset. One of the valves doesn't stop the air from leaking when the valve core is removed. I've inspected it and washed it but it still leaks out air. is this something i can warranty?

    The valves losing a little air with the valve core removed is not a problem. You still have enough time to measure and refill the sealant and the put the valve core back for full air-tightness. If you lose a lot of air please contact us on

    Thanks for getting back to me~ Yeah, the valve does leak air but I do have time to refill but I have to be very quick about it since it does leak pretty quickly. I just like how the other valve stops any air from leaking and I can take my time when filling up the syringe with sealant. I've been dealing with it for a year now and gotten good at prepping I'll get in touch with your support to see if I qualify for a replacement valve.

    Thanks and also I do love the Milkit system. I have 2 wheel sets that both run the Milkit and it makes my life A WHOLE LOT EASIER!

    Problem is small cartridges need insanely high pressures, thus their seals are actually metal not rubber. So you can't feasibly having something small and reusable. You get something the size of a milkit for more normal pressures you can reach with a regular pump and normal plastic+rubber seals.

    If only it added sealant at the same time. You could truly milkit.

    I would be curious to see how well this worked on a setup that doesn't have the tire already seated.

    Because there is no pressure loss in a hose and other valves and connectors, the milKit booster is more efficient than any other solution currently on the market - including compressors. It will seat your tire even if you have a difficult tire rim combination. It's a pity we didn't show a sequence with an unseated tire in the video.
