Hey Eric, Enjoy your Instagram site. How well do you think Gus would work as an allroad/mixed terrain bike with tires like the 700x55 Antelope Hill or 2.2” Fleecer Ridge? Giving thought to the ATB/one bike solution and am thinking about the possibilities. Somebody on the forum speculated that the Gus could possibly be an Atlantis/Jones LWB mix. Thank you and happy riding. Randy in Wisconsin
