When you’ve handled a messy tubeless set up earlier than, or struggled with getting a tire to seal with a ground pump… you’re in luck. Milkit’s tubeless Valve System and transportable Booster are designed to make tubeless setup simpler, cleaner, and doable from nearly wherever, and not using a compressor. Learn on for our first impressions…

When you’re like me, and fully remodeled right into a die-hard tubeless fan boy, then you definitely’ve most likely developed a system that works for you. My course of for establishing and sustaining tubeless tires is fairly constant at this level—each on private bikes and bikes reviewed for this web site. 1. Skip dry becoming the tire first; 2. Set up rim tape; three. Set up tubeless valves; four. Set up tire; 5. Take away valve core; 6. Squeeze sealant by means of valve into tire; 7. Reinstall valve core; 7. Inflate with a ground pump. NOTE: When you’re new to tubeless, take a look at our information right here.
To be trustworthy, I’ve by no means actually had a difficulty with this method. It really works. No compressor, no mess. When it comes time so as to add some extra sealant, it’s a bit little bit of a guessing sport although, however I determine an excessive amount of sealant is healthier than too little. And though I personally haven’t had a lot of an issue, I do know many people have points getting tires seated with out the blast from a compressor. That is the place the Milkit Valve System and Booster are available. At first look, the equipment may seem like a pair of valves, a water bottle, and an enormous syringe. Nevertheless the equipment incorporates a number of intelligent gizmos which can be fairly fascinating. As as to whether each solves an issue, I’m not completely positive…
MilKit Tubeless Valve System
The Milkit Valve System claims to supply a couple of advantages to make tubeless setup and upkeep a bit simpler. The equipment is made up of two parts: a pair of MilKit’s light-weight aluminum tubeless valves, which promise to not get clogged, and a syringe with an applicator tube that has a shutoff valve. MilKit claims that when used collectively, refilling and measuring the sealant in your tires is “simple, dependable, and clear.”
Throughout setup, this implies after seating your tire onto the rim you may simply add sealant, with the offered syringe, precisely and with out mess. Throughout my final tubeless setup, this saved a little bit of time after the tire was seated; I used to be in a position so as to add sealant with out the tire fully deflating (because it usually would) with out the valve core put in. On my first strive I forgot to let a little bit of air out of the tire—the really useful stress is 15-22 PSI—and ejected the syringe’s plunger over my shoulder, together with a half serving of sealant. My mistake. Be sure to learn the directions. From a bikepacking perspective, being able to probably service a tubeless setup with out shedding all air stress positively isn’t a nasty factor, particularly for these working giant tires that may take a little bit of effort to pump up.
The syringe has two capabilities. First, it assists with including sealant to a contemporary tubeless set up. With the valve put in and core eliminated, the included hose slides proper down by means of the valve, previous the rubber flaps, and into the tire. A small plastic regulator valve on the applicator hose controls each the stream of sealant and the air stress throughout the tire. As soon as sealant has been added, you shut the regulator, take away the applicator, and guess what? Your tire remains to be inflated!
The second operate is being able to measure the quantity of sealant within the tire with out unseating the tire, and for those who comply with the directions correctly, with out deflating the tire both. The method is fairly much like what was outlined above, however this time the tire stress ‘pushes’ the sealant up into syringe (permitting you to visually examine how a lot sealant you’ve obtained) earlier than both including it again in or adjusting the quantity of sealant. My second wheel went a lot smoother than the primary, and so long as you’ve obtained a hand on that tiny regulator, and management of the plunger, it’s fairly self explanatory.
Whereas the syringe is good and all, the actual magic is within the valves. As mentionef, the underside of every valve, contained in the tire, includes a one-way rubber flap that stops air from exiting the valve (with out the valve core put in). This not solely assists throughout setup and upkeep, it additionally retains sealant from getting into and clogging the valve core whereas out driving, which is all the time a difficulty after some time. The valves can be found in a spread of various lengths, relying on the depth of your rims, from 35mm as much as 75mm, and may be bought as a equipment with the syringe or on their very own.
Milkit Booster Bottle
The Milkit Tubeless Booster Bottle, though not fairly as intricate as your entire Valve System, has confirmed itself fairly helpful. Briefly, it’s a transportable compressor. A presta valve on the highest finish of the bottle is used along with a ground pump or hand pump to pressurize the bottle, after which the applicator head matches on any presta valve to offer a superb blast of air to help with tubeless setups. My first shot with the Milkit Booster was with Skyler in Calgary, and it’s secure to say it shocked us each at how a lot punch it had! Pump it as much as the really useful stress of between 87 and 160 PSI, take away your valve core for higher air stream, and push the applicator head firmly onto the valve. No hoses, buttons, or parts that may fail, it’s easy and efficient… and can be utilized as a water bottle in a typical bottle cage! It even comes with a screw on lid for that function.
The one hitch I see is having a pump giant sufficient to pressurize the bottle as much as the required PSI. I had to make use of a unique ground pump since my Lezyne solely goes as much as 60 PSI, as it’s designed for high-volume tires. I can solely see the water bottle side of the MilKit Booster being relevant to those that have a big hand-pump that may rise up into the 100PSI vary, which doesn’t apply to me.
So the place can or not it’s helpful? I believe it’s an important choice for many who don’t have room for a compressor and have points with seating tires throughout a tubeless setup, which is fairly frequent—a stay-at-home tubeless blaster for setup and upkeep. I’ve used the Bontrager Flash TLR Charger, a ground pump/blaster hybrid, and a Professional Workforce Compressor which was a standalone unit. Each labored okay, however had been fiddly sufficient that I’d quite strive my luck with a superb ground pump or simply borrow a compressor. Up to now, the MilKit Booster looks like a superb various. I’ve now made a spot within the van I’m dwelling in for the Milkit Booster, which is extremely simple resulting from its measurement. Milkit gives the Booster in two sizes, small (zero.6L) and huge (1L), and spare booster heads are additionally obtainable to buy on-line.
I’m not completely offered that the Milkit Valve System will resolve everybody’s tubeless woes. Possibly it’s as a result of I’ve been lucky sufficient to have profitable and pretty simple tubeless setups so far. Till now I’ve by no means actually questioned about an ‘simpler’ choice. Nevertheless, Mikit’s valves are positively distinctive and fairly fascinating, to say the least. They labored precisely as MilKit claims, each through the preliminary setup and whereas topping up sealant. Simply ensure that you become familiar with the directions. I’m additionally fairly eager to see how the one-way flaps constructed into the valves maintain up, and stop valve core clogging. I’ll make sure you put up an replace down the street.
As for the MilKit Booster, I believe it’s a reasonably good various to a compressor. I’ve discovered it fairly helpful and surprisingly highly effective for seating tires (so discover me in my van this summer season for a $5 tubeless setup).
Sellers are unfold throughout North America and Europe, and there may be distribution arrange as effectively so getting your individual Milkit Valve System or Booster ought to be doable by means of a neighborhood bike store. Take a look at the supplier web page to search out out which one. At the moment the tubeless Valve Package is priced at $56 USD at REI, and round $59 USD for the Booster.
