Tubeless is one of those great ideas that’s actually made life a little easier. Sure, tubeless can be a bit of a pain as the tyres can occasionally be hard to seat on the rim, but doing away with inner tubes greatly lowers the chances of getting a puncture, and good sealant will have that puncture mended and ready to go far quicker than changing a tube anyway.
The milKit system is fantastic because it lets you install sealant and check sealant level without having to remove the tyre from the rim, meaning once you’ve got that tyre seated the only time it should need to come off is if you puncture badly enough that you need a new one. It also removes that moment where either you’ve seated the tyre and have to remove a small section to pour in your sealant, or you put your sealant in before seating the tyre and really hope that you’re not about to repaint your walls in ‘gunk chic’. You laugh, but we’ve all done it.
One other really good thing is that you can use the system on pretty much whatever bike you fancy. Want to go tubeless on your commuter? Good idea, milKit works with that. How about your Enduro bike? Got you covered. Road racing on tubeless? Sign us up.
Helpfully, milKit’s tubeless system is very easy to install and use. It’s basically two parts: the valve and the injector.
The way the valve works is by having a one-way barrier at the bottom, which means the end of the injector can get through into the tyre but none of the sealant can come back out the same way once it’s been installed. That means that the valve core also has an extra long section as it also needs to get through that barrier to get air into the tyre, which is why the valve core looks a little different to your standard tubeless core, and you need that one to make the system work, you can’t replace it with something else (not that you’d want to).
First off, you need to install the tubeless valves (on your tubeless-ready wheels, that’s important because if they’re not tubeless-ready then the won’t work, will they). It’s literally as simple as installing any other valve. Then go through the process of installing and seating the tyre like you usually would.
Once the tyre is on the rim, let out most of the pressure. MilKit recommend having your tyres at 22psi. Remove the valve core - you can use the handy tool that comes with the valves - and measure the amount of sealant you want to put in using the syringe.
With the core removed, poke the end of the syringe through the rubber seal and into the tyre, then press inject all the sealant into the tyre. Remove the syringe, screw the valve core back in, inflate the tyre and you’re good to go. It really is that easy.
When you pump up the tyre fully you’ll probably hear some crack or popping noises as the tyre fully seals onto the rim. That’s normal so don’t worry. It’s pretty much impossible to get a tyre properly seated with no sealant in because the sealant helps to fill up all the tiny places that the air can escape. Without sealant you’ll find your tyres going down every few hours as the air slowly leaks out if they stay up at all.
If you fancy a video to show you the above process, you’re in luck as milKit have made their own instructional video. Check it out below.
