Why we do it.
Many of our best days are spent riding our tandem. Granite Tandem Design allows us to share our love for riding, racing, and traveling with the cycling community one custom bike at a time. If we can expand someone’s love for riding through our bikes, then in some small way, we believe we’re making the world a better place.
