The Nature Boy is our singlespeed cross monster. It’s as popular on the race course as it is on the city streets.
It carries on the tradition of classic steel cross bikes, with the addition of our standard AC hallmarks: beautiful lugged fork crown, internal cable routing, Hennepin Bridge dropouts, signature brazed-on seat collar, custom BB shell and our signature head badge. Everything is E.D. coated for longevity and rust prevention.
Since cross bikes are perfect for everyday living, you’ll find hidden fender mounts and two sets of bottle bosses (reinforced of course). There’s clearance for 38c tires with plenty of room for mud. The steel fork is easily swapped for a carbon model, should you want to lighten up for race season.
Race the heck out of it, ride singletrack, crush gravel or commute to your heart’s content.
