So wide
Even off of a bike it was clear from the giant crown and prairie-wide stance that the Mastodon was designed to fit even the widest-of-the-wide fat bike rubber.
The chassis can easily surround the largest tires available; everything from Vee Rubber's 26 x 5.05in 2XL Snowshoes to Bontrager's Hodag 27.5 x 4.5in. There's also plenty of room for 29 x 3.0in plus tires.
Dialed damping
The Mastodon uses damping technology derived from its well-received Mattoc and Dorado forks.
The forks are upgradable as well, accepting Manitou's Infinite Tuning Rate kit for additional mid-stroke control, and all of the seals, oils and internals are built to work in freezing temperatures thanks to Manitou's expertise in snowmobile racing.
Stiffness claims
Through the use of large 34mm stanchions and Manitou's classic reverse arch, both front and back and torsional stiffness is claimed to be improved over the Bluto. Manitou's testing puts these numbers at 26 percent and 25 percent respectively.
