Silca's Pocket Impero Hand Pump shares the aluminum construction, brass check valve, and 3 mm Milan-made leather gasket of the Impero frame pump, but it also includes design changes to alleviate common mini-pump woes. A Slide-Lock Silicone Insulating Sleeve provides confident grip and doubles as a handle lock to keep it secure in a jersey pocket. Since most mini-pumps suffer from massive efficiency losses at high pressure due to hot temperatures, the Impero Hand Pump features mirror-honed internals that reduce friction, allowing it to inflate a 23 mm to 89 PSI in just 200 strokes.
Heat is the enemy of mini-pumps. More strokes generates more friction which produces more heat and heat is wasted energy. Unlike most mini-pumps, Silca's Pocket Impero Hand Pump does not suffer from efficiency loss when hot. Pocket Impero is between a high pressure and high volume pump. At 200 strokes the Pocket Impero reaches higher pressures than any other pocketable pump ever tested in the BikeRadar test protocol, meaning that it is pushing more air with fewer losses than pumps of either high pressure, or high volume designs. The unique Slide-Lock Silicone sleeve improves grip and doubles as a handle lock when in your pocket.

Makes other handpumps insignificant and pumps twice as much volume compared to other cheaply made ones. Very durable and handy when you get a flat out on the road I was able to get mine up to 95psi with this pump probably could of gotten more but thats plenty for finishing your ride. Very well made no cheap plastic and made of aluminum and comes with a 25 year warranty! Costs more but better made and will last you a lifetime.
I especially enjoy the size. It pumps like a mad man compared to my other brand. I also like the slip on nozzle rather than a screw on. I cannot tell you the number of times I've removed the valve. The one thing I am not thrilled by is the lack of a frame mount that attaches to the cage screws. I have to other brands that not only have a mount that can be fitted under the cage but one brand also has a mount incorporated into the cage. At the price point of the silca, a mount would be a nice feature.
Terribly expensive but high quality construction like all Silca products. I primarily use Co2 but if you run out cartridges or the inflator fails it's nice to have a pump that will RELIABLY inflate a tire enough to get home. Got tired of lesser pups failing when I needed them the most. Did some tests on a 700c x 25c tire it took 250 strokes to reach 80 psi, 200 strokes to reach 75 psi and 50 strokes to reach 25psi. I typically use 12 gm unthreaded cartridges ... I use this pump for the first 50 strokes and top off with one CO2 cartridge- that will give me 100 psi.
The little decorative o-rings you see on the butt of the pump are a joke- isn't going to take long before they peel away and you lose them.
