SILCA EOLO IV Co2 Regulator | Compact Design with Turn Screw Control Valve | Presta and Schrader Compatible | Universal Co2 Cartridge Thread

It's small and light but works better than anything else out there. Slips on & off quickly. Twist valve allows for precise control of air without leaking.The top negative comment says that you can get other regulators for cheaper. True enough, but with Silca you're paying for quality. It's small so it doesn't take up as much room in your jersey. Most important, it's reliable.

I like the quality. They are compact and easy to use. Great for in a bike pack or tool box.

Replaced another brand CO2 inflator with this Silca. I had trouble with other brand having to screw on and off and unscrewing the valve stem when taking it off. Josh at Silca is an absolute detail fanatic so I knew this would be researched to the Nth degree. Super light and small. Twist valve control allows for CO2 to be delivered as slow or as fast as desired. So far, I’ve been able to use a partial cartridge, close the valve and even maintain CO2 in the partial cartridge through the next day without leaking out. Very satisfied so far.

I had a different brand inflator that was my favorite for the past several years.But I bought one of these a couple of months ago and it's the best I've ever used in my 30+ years of dealing with flats and misfiring inflators.Takes up very small space in your repair kit, easily to use, easily to set on the value and haven't had any CO2 cartridge misfires so far....so I'll be buying a couple more for my other bikes repair kits. Great product!One caution, The air flow turn knob can unscrew and separate from the inflator. Make sure it’s secure after use or you could lose it.I saw a review here that the Green colored is for Schrader valves and Red for presta. Nothing in the product details says that. I have a red and a green and both work on presta valves. I assume that both would work on schrader valves also as it says in the product details,

Machined aluminum high quality. Used during a recent run down Greens Creek off Monarch Crest trail. Worked flawlessly.

Compact and functional. Very easily fits into a saddle bag (my primary goal) and threads easily onto CO2 cartridges. Silca is a known brand for bike pumps and it shows. Well constructed, cool colors. Cons: none yet, haven’t had to use much.

First time worked great, regulated the outflow of gas. Then it blew out from the top even when closed. Wasted two canisters and got stuck on the side of the road. Took it apart and it seems to work now but can't trust it. Furthermore, my bag got wet and somehow the paint came off this thing. Normally, I love everything they make, but this was definitely a miss.

I’ve had to use this several times, unfortunately. Love the size, easy to use. And you can stop part way if you don’t need a whole CO2. I’ve tried several CO2 inflators over the last 5 years, this is my favorite. Worth the extra $ compared to the super cheap ones that will eventually fail.
