The Mastodon is not a modified or repurposed trail fork compatible with large tire dimensions, but rather it is a fatbike fork made to improve any ride regardless of how low or high the numbers on the thermometer read. To create such a dynamic fork required all-environment and all-temperature performance testing that took the R+D staff to some of the most inhospitable testing environments in the world. To earn its place within the Manitou family, the Mastodon passed performance and reliability testing in both real world and lab scenarios at temperatures as low as -40 degrees. The Dorado Air, seals, lubricants, and all other internals are proven for all-weather performance, no matter how extreme on either end of the temperature spectrum.
