That tire lever + valve end is brilliant.

The EOLO IV is just perfect: great quality and fits in my compact saddle bag.

[Hur]

I’m a very positive person and rarely leave anything resembling a negative comment (even if it is for an obsolete model), but I’m going to have to this time. In all my years of buying Silca (pre-and post the Italian to American conversion.), I have loved every single thing that has come into my possession, except the three Eolo III’s that failed on me a few years back. For some reason, every time I used one, it would blow out a gasket. I would say it might be user error, except for the fact that I have never once had another brand inflator fail on me in that way. I know that product doesn’t exist anymore, and I have since forgiven and bought the very nice Eolo IV — but I have apparently not forgotten. 😁

Schwinn had a Pocket Power pump that used a BB gun CO2 cartridge back in the 1970's.

EOLO is not Italian for wind, but for AEOLUS, the god of wind.

Josh is following the "Scotty" from Star Trek formula for his estimated weights.
Kirk: Mr. Scott. Have you always multiplied your repair estimates by a factor of four?
Scott: Certainly, sir. How else can I keep my reputation as a miracle worker?

[chrisbuttine]

I have the original brass one and still use it. My wife bought me 5 or so years ago a new US Silca distributed a shown at 6:50 in the video one - It failed a few years ago even though it never saw much use. The head just fell apart when taking it out of my saddle bag.

I still have some Silca frame pumps with campy heads. And, the large track pump.

[fosterhunter]

I like the last one with the lever the best. Do you offer a version without the lever? Im thinking you could just keep it on your valve and screw in the CO2 cartridge whenever you need air. Maybe even keep the cartridge on the valve.that would catch eyes.

[julianallen]

I'm an Solo 3 fan, I've seen too many riders screw the Co2 onto a 2/4 style with the knob and dump all the case into the air as they didn't close the valve after using it the last time!

[borzumo]

would love to see demonstrations with 23 and 25 tire, amount of gas and pressure to keep in mind

[jesusgargo]

Can you use the cartridges more than once when they are opened with the EOLO IV?

[albertdee]

Add in the weight of CO2 cartridges along with the EOLO you are very close to the weight of an electric mini pump (CYCLLUS AS2 pro 120 g) that can pump 4-6 tires. One does not get the waste of the cartridges nor does one get the clattering of tubes in their seat bag/back pocket (and more environmentally friendly). downside is cost is initially more. Thought maybe at the end you were going to announce a Silca electric pump to replace EOLO.

[sosllc]

I have been having issues seating my tires with CO2 after a flat. Should you just let it rip and go full gas or feather the flow? I only need 62-65 to seat the tire but rarely get there

[gerardcummins]

recently switched to tubeless using Silca’s new sealant. Before that, I carried a repair wallet with a mini pump and TPU tubes—super light and kept my Aeroad saddlebag-free. Now with tubeless, I’m worried a puncture might unseat the tyre, so I bring two CO2 cartridges. Is that concern valid, or would a mini pump be enough?

[deniskfender]

Rechargeable pocket pump is the next stage

[cxbkpmf]

Those vintage parts are so cool. But why was aluminum not used back then?

[Adonis-qjnq]

While I love Silca products and generally think the product line is on the cutting edge, I have to say the pump side of things are starting to feel antiquated. I have moved to portable electric inflators like those offered by Cycplus. I paired them with a Silca chuck. I even packed one in the saddle bag. Electric inflation is so much better than the old manual labor way. I’m never going back. It would be nice to see some electric inflators from Silca.

[roilev]

Hi Josh, which one has the highest gas flow? I use CO2 for seating stubborn MTB tires and I need the highest flow possible.

[Kzuke]

Are the levers attached to the inflator head the same as the Silca Premio levers? They look similar, but there is no direct statement to this effect in the product details on Silca's website?

[yellowglider]

“Eolo” is the name of the god of the winds in antique Rome. Italian for wind is “vento”.
