As incredibly difficult as cross racing is, cross bikes have to be even tougher. A great cross bike is able withstand not just brutal weather, aggressive racing, and unavoidable spills, but also weekly travel, whether in a car or stuffed into a bike bag in the belly of an airplane. When we say our cross bikes are proven to shake off all of that abuse with ease, we mean it.

The Firefly-equipped Bitchn Grit racing team flies back and forth across the country dozens of times per year. In four years of sponsorship, they have raced their bikes to elite top tens, podiums, and wins (including Dani Arman’s 2019 women’s 30-34 national championship!) over and over again. And in those four years: not a single issue with any of their frames. Just worry-free, ultra-fast racing against the country’s best, mixed in with springs and summers full of gravel riding, demanding training, and not-uncommon mountain bike trail exploring.

Combine that reliability with our industry leading custom design and manufacturing and you’ll understand why your dream cross racing bike is a Firefly.

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.

The bike is unbelievable. You guys really delivered in every way possible. I love the solid and connected feel. The geometry is only slightly different than my R3, but it is incredible how much more comfortable it is. I knocked out a three hour ride the other weekend and got off the bike feeling like I only rode half that time.
