Ripping a set of banked turns without touching your brakes.

Getting to the bottom of a hill and screaming uncontrollably with joy.
Eating and drinking and slightly overstating how rad you got after a ride.

We love mountain biking.

We love building mountain bikes that deliver those same moments of exhilaration. We love surprising people with how capable a well-designed hardtail with a custom geometry designed specifically for your riding style and terrain can be. And we especially love that a well-built titanium mountain bike can literally be as good as new after decades of hard riding.

We can build mountain bikes for every wheel size and any tire size up to 4” fat bike tires, and for any use from single track trail riding to bike packing to epic winter snow rides.

In a word, the Firefly is a revelation: the handling is nimble and responsive (no more toe overlaps!), I’m able to rail around corners with confidence, and getting (and staying!) on the drops is no longer an ordeal.  I’ve come to expect Ti to be a super light material, yet I’m still surprised at how remarkably it climbs.  As for the usual suspects describing Ti’s ride quality: stiff, responsive, and comfy — yep, all true.  Taken together, these are stellar qualities that I would have never expected to find on a single bike.

And then there’s the process of getting the Firefly itself.  First, there’s the sheer craftsmanship involved with building the frame: the welds are stunning and the tube surfacing with anodized bits are awesome to see in person.  The custom tech with the dropouts and CS yoke has sparked many conversations with my fellow bike nerds in the office.  Most notable, the time you kindly spent going over frame numbers has instilled an appreciation for bike geometry and fit: that finding those numbers can be done methodically without needing a pro fitter or fancy jig.
