# Unior USA

> Unior USA is the U.S. source for professional Unior bicycle tools, Sinter brake pads, and Bleedkit hydraulic bleed kits — European-engineered equipment trusted by WorldTour race mechanics and skilled home mechanics.

Unior USA, operated by Euro Tool Works, LLC, of Ballston Spa, New York, is the independently owned U.S. importer of Unior bicycle tools and the partner brands Sinter and Bleedkit. The catalog covers professional workshop and home-mechanic tools for every system on a modern bicycle, and carries a lifetime warranty on Unior hand tools.

## About Unior

Unior d.d. was founded in 1919 in Zreče, Slovenia, by the engineers Milko Bremec and Walter Mach. It is one of Europe's largest drop-forging companies and has developed bicycle-specific tools alongside the world's leading race mechanics for decades. Unior hand tools have been in WorldTour service since 2016, and Movistar Team lists Unior as a bike-tools partner today. Tools are forged and finished in Unior's own Slovenian factories.

## Workshop expertise

Unior USA is run by cycling-industry veterans — Bruce Fina (30+ years in the cycling industry, founder of Pedro's USA), Fil Fina (suspension and lubricant engineering), Travis Barnes (former NICA coach), and Jack Arnold (former shop mechanic). Tools are specified and tested by people who have serviced bikes professionally.
