This thing is like functional art, just what bicycle or bicycle product should be. I almost can't wait for a flat to get to use it. Silca made it common sense, smaller than its competitors, and easy to use. Perfect.
Say what you might about their pricing, but Silca makes some quality gear! After some frustrating experiences with some other inflator heads I switched them out for Silca. They just get it right.
It's the absolute minimum because it almost never gets used, but when I need it, it's there and reliable.
Easy to use it screws on tube stem and you're ready to fill tube no lost air. Nice and compact, Silca puts out
good quality products.
Haven't had to use it personally but I've lent it to other riders when they flatted and their dial turn CO2 inflator heads fail to work. Simple, effective, and it just works.
