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

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.

As with most things Slica, this is a well-thought-out product. It's smaller than I expected (a good thing), packs away well in the bike tool bag, and works as expected.

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

Good product

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.

Please keep it in a ziploc bag, as the plastic knob is easily lost. Also, dust is not its friend.Easier to use than most and thoughtfully color-coded (red for Presto, green for Schrader).Unlike some competitors with pressure activation, this one’s strictly rotation activated. Holds a partial charge indefinitely.Lightweight and small, easily lost. Use a bag

Ultralight, precision-crafted, and full-featured. I love the precise flow control and ability to thread onto the valve stem.

Not worth the price & Quality... can get EXACT SAME Item for much less price. ..... I love the same exact item from Pro Bike Tool & BriskMore for nearly half the price and yet theirs comes with CO2 sleeve ..... This seller does not include CO2 sleeve and charge way more for even lower quality item.NOT WORTH THE PRICE AT ALL.
