Ripping a set of banked turns without touching your brakes.
Clearing a rock garden that seemed impossible two months ago.
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.

A huge thank you for building a beautiful steed once again, that performed fantastically at DK. I’ve never really ridden trails before and had to learn on the fly, but the bike made it all so easy to adapt to the unfamiliar conditions. I was able to ride sections of downhill gravel at speeds approaching 60 kph and it felt rock solid.
