Tubeless tire maintenance gets simpler with the milkit system

Crowdfunding a flat-free ride: milKit launches campaign on IndieGoGo
Clean, safe, simple: Tubeless made easy

The milkit system is an innovative system to make tubeless sealant installation and maintenance simpler and more foolproof. The system utilizes a proprietary valve stem and an injection syringe. The special valve stem has a secondary closure valve located on the bottom, so when you remove the valve core air doesn’t escape. Otherwise, the valve stem acts as a normal Presta valve when adding or releasing air. The injection syringe has a long needle that pushes through the secondary valve into the internal wheel cavity. When the valve stem is positioned downwards, the needle can touch the bottom of the tire and extract out the sealant. This design gives you the current sealant level, and it can then be injected back into the tire after verification, never losing any pressure during this endeavor. The secondary valve is supposed to help with clogging issues on the stem, which is always a common malady with tubeless stems.  They are currently crowdfunding the project on IndieGoGo at www.igg.me/at/milkit


Press Release

Zurich. April 27, 2015 – Those of you who ride tubeless know the problem: Flat tires due to dried out sealant. With milKit this is history. Riders and racers can quickly measure and check their remaining tire sealant with a simple, portable kit, adding sealant as needed while leaving their tires on the rim. The Swiss invention comes onto the market this summer. In order to boost the launch and to cover a part of the production costs, the inventors are starting today a campaign on the crowdfunding platform IndieGoGo (www.igg.me/at/milkit). During the first three days of the campaign, backers benefit from an early bird discount. The campaign will run until the end of May with the goal of at least 25,000 USD.

Tubeless tires have more traction, a lower rolling resistance and are more puncture proof than traditional bike tires. But they can also be a pain to maintain, potentially slowing you down in the middle of a race — unless you’re riding with milKit.

Until now, the maintenance of tubeless biking tires was tedious. milKit (www.milKit.bike) eliminates the guessing game: Professional and amateur riders alike check and add sealant quickly and easily. A milKit comprises two easy-to-install valves that are compatible with all standard rims and a custom applicator. Key advantage: No air escapes from the tire when the valve heart is unscrewed.

With the applicator, bikers remove, inspect and inject sealant whenever needed through the valve, while their tires remain on their rims, no mess or fuss. A rubber flap on the patented valve prevents the sealant from getting into the valve, thus no more valves clogging. The tire stays on the rim, the air inside the tire and the hands clean – a quick and simple solution for a safe ride.

Installation:

  • Installing milKit is easy: Insert the special milKit valves like usual valves in rims. 
  • They fit to any standard rim.
    Pump the tire to 1.5 bar / 22psi 
  • Insert sealant with the milKit applicator and keep your hands clean 

Advantages:

  • Save time: Measure and refill sealant without deflating the tire. 
  • No more guessing games: Riders will always know exactly how much sealant is needed 
  • A rubber flab prevents sealant from filling and blocking the valves
  • Clean hands and simple to use 

milKit makes tubeless technology clean, safe and easy. 

IndieGoGo: seed money for a flat free ride 

 The manufacturing of tools for the production of milKit costs 65,000 USD. On the crowdfunding platform IndieGoGo the inventors of milKit are launching today a campaign to cover at least a part of the production costs. In order to succeed, bikers must crack the mark of 25,000 USD. “On IndieGoGo mountain bikers from all over the world have the opportunity to support our project financially. And those that pre-order milKit, will be one of the first to use milKit,” says Sven Rizzotti, co-founder of milKit – Sport Components AG. “The more people we reach with the campaign, the more mountain bikers can do what they love to do – carefree mountain biking.” During the first three days of the campaign, backers benefit from an early bird discount.


Who is milKit?
The idea for milKit was born during a mountain bike trip in the middle of nowhere around Moab (USA) – with a flat tubeless tire due to dried out sealant. A problem that those of you that ride tubeless will understand, as you never really know how much sealant is left in the tire, unless you deflate and dismount your tire, which no one really wants to do. That’s why the Swiss mountain bike addict and product development engineer Pius Kobler started to puzzle over an easy to use solution. Now, one year after the first homemade prototypes, countless test rides and the foundation of Sport Components Ltd. with another biking enthusiast and experienced company founder Sven Rizzotti, milKit is ready to be launched to the market.
