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.

Okay, one last time, this is the best bike in every respect possible. It is comfortable, it is smooth, it corners like it is on rails and it is the Bat Bike. It does everything perfectly. I can’t remember the last time I could not wait to go for a ride. Everyday is Christmas morning and I am a kid with a new bike. Thank you for listening to what I wanted and building the perfect bike.
