As the oldest continuously produced model of carbon fiber bicycle frame in the world, it has evolved to a state of perfection and value unmatched by any other frame.

Founded upon the DNA from our road frames, we designed our Adventure platform to be as versatile as you. We build each frame to accept 700c, 650b, or both. The slackened head-tube and seat-tube angles allow for confidence on loose gravel roads, but with all the performance features to keep-up on the weekend group ride. If you prefer randonneur Adventures with frame bags, fender or rack mounts, you can travel with confidence and comfort. We build every frame with your exact needs in mind. The Adventure is yours!
