Manitou Mastodon Comp Suspension Fork - 26", 100 mm, 15 x 150 mm, 51 mm Offset, Matte Black, Extended

Availability: In stock (2)

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 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.
