Magnum/Mattoc Expert/Pro IRT Upgrade Kit

Take full control of your fork’s performance with the Manitou Magnum/Mattoc Expert/Pro IRT Upgrade Kit. This precision upgrade adds the Infinite Rate Tune (IRT) system—giving riders the ability to fine-tune both mid-stroke support and end-stroke progression for a smoother, more controlled ride. Whether charging through rough descents or dialing in traction on technical climbs, this kit delivers the adjustability serious riders demand.

By separating mid-stroke and end-stroke tuning, the IRT design improves small-bump sensitivity while maintaining confidence-inspiring bottom-out resistance. The integrated volume compensator ensures balanced support across the entire stroke, letting you push harder without harsh ramp-up or loss of traction. Perfect for riders who want to get every ounce of performance out of their Manitou Magnum or Mattoc fork.
