About Silca Few brands have been more intimately connected to the last 100 years of cycling than Silca. The Italian-born brand’s legacy of legendary quality has seen company’s pumps being passed down through generations of professional mechanics and cycling enthusiasts – riders who value the experience of bike maintenance and understand its performance value. Now based in the US, Silca’s heirloom quality pumps have been joined by a growing selection of thoughtfully designed and stylish accessories. After more than 18 months of testing, use and abuse at the top levels of racing, Silca give you the SuperPista Ultimate Hiro Edition. Combining the multi award winning SuperPista Ultimate Pump with the multi-award winning Hiro Locking presta chuck, the Ultimate Hiro edition puts the identical tool used across the Pro-Tour in your garage. Ultimate Hiro Edition utilizes a custom hose and magnetic Steel End Nut on the chuck, allowing the Hiro chuck to to be docked magnetically when not in use. Hiro V3.0 is 15% smaller in all dimensions than the original Hiro and utilizes a new plated steel wimg design which allows for better compression control. New single stage 254 Gasket allows the chuck to be placed over the valve with NO interference or pressure, and then be locked into place with the new low profile lever. Hiro V3.0 allows for one handed use in ALL disc wheels and on ALL valve extenders. Now in use by some 50% of Pro Tour teams and hundreds of shops and professional mechanics worldwide.
