There's no doubt that tubeless tyres are one of the best things to happen to mountain biking, but getting them seated can be a right pain in the arse, even in a workshop or garage. Doing it in the great outdoors can be even more of a faff, but Milkit's new Booster tubeless inflator looks like a very tidy and extremely portable way around this issue.

If you've ever tried to seat a tubeless tyre with a hand pump or struggled with canister after canister of CO2 on the trailside and you haemorrhage sealant onto the countryside, then Milkit - they of the clever tubeless valve stem and sealant injector system - has come up with an extremely cunning and portable inflator setup.

Basically, it uses a specially reinforced bottle - fans of the classic Sigg item will see a certain resemblance - and a screw in head that allows you to build up to 160psi of pressure inside with a normal pump before discharging it into your tyre by pressing the head onto your valve.

The neat bit is that the bottle itself will fit into a normal bottle cage, comes with a conventional cap and can be filled with water, so it functions just as normal until you or a friend has a tubeless issue. Then you just empty out the contents, connect the special inflator head and get pumping. The head lives inside a little bag, so you can throw in in a pack without it getting gunked up or dirty.

It seems like a pretty damn neat solution for anyone taking on a big ride where they might be out of reach of any mechanical backup for some time - or just anyone that hates the idea of having to put in a tube because they've rolled their tyre off the rim or otherwise had an issue.

The bottle comes in either a 1l or 600ml version so you should be able to squeeze a setup into any frame and you can buy either as a complete kit or any of the parts alone. The high volume kit is £43, the lower volume £40, the head alone £25, a 1l bottle £20 and a 600ml item £16.

As it's both mega-portable and one of the cheaper inflator systems on the market, we're really quite keen to see how it fairs, so check back for a full review soon.
