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 4.6” fat bike tires, and for any use from single track trail riding to bike packing to epic winter snow rides.

I know you probably here all the time how great your bikes are but I wanted to let you know that this year at Unbound, my FF1455 was the perfect bike for the mud, hail, torrential rain, wind and water fest.  The only thing weather wise I did not encounter was a tornado.  Because you built the wider chain stay, I ran 50 G One RX tires and had not an ounce of mud issue.  I literally walked 50 feet the entire day due to the 3.5 feet of water in the tunnel.  I could have road it but did not want to submerge the bottom bracket.  Ended up finishing at 14:07 (20 minutes spent between 2 flats)  beating the sun.  Considering the weather, I was pleased with my performance.  The Firefly was absolutely amazing and chewed up everything Unbound threw at it.
This bike has never disappointed me once between all the rides including SBT, Bighorn, and now the ultimate test of Unbound 2026.
