The isolated hills of Romania, remote mountain passes in Peru, 350 miles of the roughest gravel Kansas has to offer, Trans-Europe epics: we are endlessly inspired by the places people ride their Firefly All-Road bikes. Those experiences have pushed us to continually refine every detail, making the bikes more capable, versatile, durable, and beautiful than ever before.

In 2015 we introduced our proprietary Adaptive Butting process, which reduces the weight and improves both strength and ride quality of every full titanium bike we build. In 2017, the increasingly demanding riding of Firefly riders across the globe led us to create our custom 3D-printed chainstay yoke, a tiny but crucial component that helps us build All-Road bikes with industry-leading tire clearance and the shortest possible chainstays, all without any reduction to frame strength or stiffness. Shortly after, we applied that same technology to our custom 3D-printed flat-mount disc dropouts, making our frames stiffer, lighter, and even more precisely aligned than ever before.

Those incremental improvements, all inspired by the incredible community of Firefly riders, have continued to this day. You could call it real world R&D, or experienced-based design. Whatever you call it, it’s what makes our All-Road bikes the best they’ve ever been.

Ascents, descents and rough as guts coarse-chip roads. The bike was superb. I’ve never felt so confident descending and the reduction in road buzz was very noticeable.
