One bike to do it all. Really.

Tire Clearance: 700x38mm, 650x47mm
Brake Style: Flat-mount disc
Ideal terrain: Good roads, bad roads, dirt roads, gravel roads, fire roads
Materials: Titanium or Ti-Carbon

We are asked all the time to build one bike that can Do. It. All. One bike that is as suitable for fast group rides on the road as gravel racing as all-day mixed-terrain rides where you find yourself on a single track trail “by accident.” We’ve been making that bike for years, to be honest, but now we can do so better than ever thanks to new technology like our proprietary 3D-printed chainstay yoke and dropouts, dramatically expanding the tube selection possibilities for each bike.

When designing for versatility, there is simply no substitute for expert custom design to create perfect handling no matter the tire selection, and no matter the ride. Custom means we can make the fit and handling aggressive enough for fast group rides and still stable and capable on a wreckless gravel descent. Custom means we can design and machine the tubing to be as efficient as modern carbon race bikes and comfortable for your all-day weekend escape. Custom means exactly the tire clearance, components, and features you want. Nothing more, nothing less.

We’re not saying you’re going to want to sell your other bikes, but you might.

Bike companies are constantly searching for the perfect balance of stiffness, comfort, and lightweight. Ironically, the material key to that balance, the material of dream bikes, has been available the whole time. That material is titanium, and we have been honing our titanium frame-building skills crafting custom frames since 1995. We start with the best quality 3/2.5 titanium tubing sourced from top aerospace tubing suppliers. After we have designed a geometry and selected tube dimensions to suit your riding style, we machine, externally butt, bend, and miter the tubing all in-house to meet your bike’s specific needs. In other words, every single element of the construction is custom for you. The result is a velvety smooth, light, and efficient bike with unrivaled durability and unlimited finish options. With titanium, your dream bike today can be your dream bike in 20 years.

Our goal has always been to make the very best bike possible for every riding style, and titanium’s exceptional combination of versatility, durability, ride quality, and light weight have always been at the heart of achieving that goal. At the same time, carbon bikes are everywhere for a reason. When done right, carbon is light, stiff, strong, and quiets road vibrations beautifully. By blending custom mandrel-rolled, tapered carbon tubing with precision-machined titanium lugs and chainstays, we are able to combine the best qualities of both materials into a single, extraordinary frame. The result is a truly high performance bike that is slightly lighter and stiffer than a full ti frame, all while maintaining the fully custom design, superb ride feel, and unmatched attention to detail that set all of our frames apart from the crowd. This is the pinnacle of ride quality, aesthetics, and frame design.

I was finally able to take my Firefly out this past weekend. It was a dream. I love the way it rides and like I told my wife, it feels like it was built for me, which of course it was. It’s amazing how well you were able to translate requirements and design into a reality. Please pass along my thanks to the entire Firefly team.
