A steel hardtail for anything from flowing single track, to epic all-day rides. Our old friend Joe Murray, mountain bike hall of famer, two-time U.S. mountain bike champion, and probably the most respected name in steel hardtail design, helped us design the Flo. Our goal was to build the ultimate go-anywhere-in-the-world ride. With Joe's frame geometry and Reynolds' 631 air-hardened steel tubing, the Flo delivers a ride that's so smooth, yet lively, that it's hard to believe if you've only ridden aluminum mountain bikes.
