Fits all Mattoc Pro/Expert 26" and 27" forks as well as the Magnum 27+ and 29+ forks.
Adds a second individually tunable air chamber to the positive air side of Mattoc & Magnum forks. Second positive chamber can be used to manipulate the spring curve throughout the stroke, either adding or removing progression depending on the intent as the positive air pressure and the IRT air pressure interact throughout the travel.
Easy install to replace a top-cap, full setup instructions included.
Dorado version also available.
Note the IRT doesn't fit the Mattoc Comp as they use a lower grade aluminuim stanchion with smaller ID.
