Overview
Mastodon is the real-world trail suspension for fatbikes. This fatbike fork delivers all-temperature performance, working equally well in winter or summer, soaking up chatter and big hits. This fork fits up to 26×4.8” / 27.5×3.8” tires on the snow, or taking on shimmering hot sand like a pro. All-temperature performance born of frigid winter ride-testing. 34mm trail chassis is stiffer and steers more precisely than any other fatbike suspension fork.
