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.

    That’s what I was waiting for.

    I finally got to ride it this weekend. I’m very happy so far. This fork floats over stuff my old fork cringed on. I can hit stuff and not worry about the outcome. It feels super stiff in a very good way. And I’m loving the compression set-up. Very nice. We will see how it goes. Let’s ride.

    Great fork

    I have been waiting a year for this to get back in stock and it was worth the wait! It has really raised the performance of of my bike. It flows effortlessly over those technical downhill sections and those technical climbs.

    Glad to hear we were worth the wait! #manitoumtb #scienceofsmooth #reversearch #manitoususpension

    Great addition to Mukluk

    I wanted some suspension when I was running my Mukluk in 29 plus mode. This fork works very well. I don't notice any flex, and the suspension works effortlessly. Had to wait a year for it to get into stock due to supply issues, but I'm happy to finally get it. Going from rigid to 120 mm greatly slackened the head tube, but the increase in BB height doesn't appear to impact the balance or handling. Unsure if I will run the suspension in the snow with the fat bike tires.
