Silca Impero Ultimate II Frame Pump The Perfect Roadside Option No matter how far you're riding, you should always have a hand pump with you just in case a flat happens. Sometimes a mini-pump takes too long, so having a longer frame pump makes more sense. The Silca Impero Ultimate II Frame Pump has been updated to use a two stage gasket, and leather piston. It has an all aluminum construction, brass check valve, and silicone bumper for paint protection. The pump is available in several sizes to fit your frame. If your pump falls between two pump sizes, we recommend going a size down.
