Originally designed in the 1950s when the Bianchi-Pirelli team requested a pump that could fit under the rear seat of the Fiat team car, the Pista pump quickly became an icon of professional team cars and mechanic workstations at 6-Day track events around the world. The compact form of the pump, and the ability to lay completely flat, allow the pump to take up minimal space in a trunk, duffel bag, or larger tool kit, making it a true icon of the sport amongst the cycling cognoscenti. In 2017, we took all of the qualities of the original Pista and introduced a re-engineered, limited-edition version of the pump with the iconic Molteni orange barrel to celebrate 100 years in business. These modern orange pumps were initially meant to be a limited-release product to celebrate our heritage, but the positive response and demand for the product have continued. As we're now in our second century of making high-performance pumps, we're pleased to make Pista part of our permanent floor pump line-up and will offer it in a modern red livery moving forward. - Durable, high-strength steel barrel - Compact ash wood handle with hose guides - High-efficiency SILCA leather piston assembly - Brass check-valve assembly - Long filler hose with integrated Schrader chuck - Push-on alloy Presta chuck with bleeder valve - Rated to 220psi

Pista Plus is a floor pump that's built to outlast the rest of your cycling equipment.

Pista Plus features a three-footed aluminum base and a full-size lathe-turned ash handle. The chuck dock on Pista Plus secures the chuck at the Schrader chuck allowing the rider to swap the standard chuck out for our HIRO chuck or Disc Wheel Adapter while retaining the ability to secure the hose to the pump. The large 64mm gauge is accurate to 2% and features a high-contrast face design. - Durable, high-strength steel barrel - Full-size lathe-turned ash wood handle with hose guide - High-efficiency SILCA leather piston assembly - Brass air bridge and check-valve assembly - 2% Accurate, heavy-duty 2.5" (64mm) gauge rated to 220PSI - Integrated Schrader chuck plus press-on alloy Presta chuck with Bleeder valve

The factory replacement for SILCA Press on Disc Chucks. The 252 replace the classic SILCA 25.1 gasket after more than 20 years in the market. This unique gasket borrows from industries which require air-tight seals in the harshest of environments. The 252 gasket utilizes a high tech, full synthetic elastomer base material. It tests to a life expectancy of more than 5X the carbon filled rubber or Buna-N materials used previously. In tests with a major disc wheel manufacturer, the current SILCA Disc Wheel Adapter with 252 gasket excelled by posting a blow-off pressure of 393psi where other designs were unable to reach 120psi. Older versions of the SILCA Disc Wheel Adapter will still benefit for the new gasket, but have a lower hands-free max pressure.
