What makes the Silca pumps better? Are they just made better with better materials?
That is a good price.
In my opinion yes they are designed and made better. The Impero isn't impacted by heat from pumping like 99% of other hand pumps. The gaskets are also replaceable. It's basically theoretically the last hand pump you'll need to buy. Silca pumps are legendary for their longevity. I have a floor pump that is 30 years old and has gaskets replaced a few times and it can still pump to 120lbs. Heck a long time ago my only pump was a Silca plastic frame pump. That thing pumped tires for 15 years until it got lost in a move.
