This is a historically premier pump. Built for years in Italy, and American company purchased the product and continues to make a pump with the best parts available.
For those of us who check tire pressure regularly and run our tires on high pressure, this is the pump to use.
The only drawback I can find is when I inflate by tires to 130 psi, the slip on Presta chuck will leak air. By contrast, the Lyzene pump locks on to the Presta valve and will take inflation as high as I dare pump it. Both have a bleeder valve to relieve air pressure before removing the chuck.
The big advantage to the Silka Pista pump is its lifetime warranty and the availability of replacement parts.
I bought one in 1984 and have used it dailyweekly since. I've replaced the hose but didn't like the hose clamp and so whipped it with heavy thread. It's only had the brass presta chuck and I've replaced the rubber gasket many times. I've swapped out the leather 731 gasket probably once every ten years. Maybe I should look for a new gauge as after 30 years of being pressured I think it reads high. Or just plug it off, and use a hand gauge.
If you want a bike tool that's worth more than your bike, and would rather have your bike stolen than lose this pump, you know what I recommend. I like the simple rebuildability.
Watch the shaft diameter, when they sent manufacturing to Asia they reduced shaft diameter (like the Super Pista thumbs down)
