2024 Manitou Mastodon Comp - Gen 3

The Mastodon not just a modified fork tweaked to fit large fat bike tires. It's designed from the ground up as a fat bike fork, enhancing your riding experience, regardless of the temperature. Crafting such a versatile fork demanded rigorous testing in some of the harshest environments worldwide, conducted by Manitou's dedicated R+D team. To secure its place in the Manitou family, the Mastodon underwent extensive real-world and laboratory testing, enduring temperatures as frigid as -40 degrees. Every component, from the Dorado Air system, to the seals and lubricants, has proven its capability for unsurpassed, all-weather performance, no matter how extreme the temperature swings.

In addition to these advancements, the Mastodon features IVA volume adjustment, enabling precise fine-tuning of the air spring curve. This adaptability caters to an extensive array of conditions, riding styles, and individual preferences, ensuring an optimal setup for every rider.

Key Features:

  • 120g of weight savings from the previous model with new crown, legs and internals.
  • Expert air allows for internal travel adjustments with no added parts. New travel spacers account for negative air volume change, so the 80mm fork has the same initial stroke feel as the 140mm.
  • Expert Air spring systems contain a unique balancing valve that equalizes the positive and negative air chambers during the air fill process. This gives the spring rate a consistent feel without any flat or dead spots in the stroke, along with giving riders of different weights the same initial stroke feel. Expert Air has identical performance to DoradoTM Air in a more cost effective package.
  • Incremental Volume Adjust (IVA) modifies the volume in the positive air chamber with self contained spacers dictating the position of the IVA piston. This allows the main air spring ramp-up to be tuned to the rider weight, style and conditions without the need for additional parts.
  • Absolute Plus (ABS+) is a shim stack based damper that features external incremental Low Speed compression adjustment.
  • New tune increases wheel traction, rider comfort and control.
  • New crown is 94g lighter, with increased knob clearance. 44mm offset to match modern fatbike geometry for precise handling and increased traction.
  • Front brake routing allows the user to use the same length brake hose from their rigid fork, or other suspension fork. Updated casting with non threaded compression rod holes for ease of service. New arch ribs for increased casting stiffness.
  • Tire diameter clearance is 2mm shorter that current EXT model, with a 6mm reduction of axle to crown.
