Manitou Mastodon Comp

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. Extended ride height versions fit up to 26×5.15” / 27.5×4.5” tires. Standard ride height versions fit up to 26×4” / 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. Order your 2021 Mastsadon from FBC and if you pick up in store we’ll install it for you free of charge. Call 844.464.BIKE after ordering to book your appointment.
