About
About
The Blackthorn C frame blends a stiff carbon fiber chassis with our progressive trail geometry and Split Pivot suspension design. The result is a well-balanced platform for an all-mountain bike that descends with gusto, rails through features, and makes climbing up for lap two as painless as possible. The Fox Float X Factory shock delivers 140 mm of travel to guide you through whatever the trail serves up. On-bike cargo features hold your tube, pump, and repair kit, and more on the frame to lighten up your hip pack — or allow you to ride pack-free. We made Blackthorn C the best all-mountain bike frame around. Take it and make it your dream bike.
