“Fat is where it’s at!” The Indigo Fat Bike represents the epitome of titanium adventure-ready fat tire bikes, tailored for extensive excursions through snow, sand, or gravel. Built for a 26” wheelset and accommodating tires up to 2.4” in width, this powerhouse excels in a variety of terrains. Its remarkably light titanium tubing ensures exceptional agility, and it’s available with either a carbon or titanium fork, making it ideal for snowy environments where rust is a concern. This model can be built as a geared version with hooded dropouts or single speed version with slider dropouts.
