    The Corset is available to fit the following sizes and models of Fox air shock:


    • 7.25 x 1.75
    • 7.50 x 2.00
    • 7.875 x 2.00 (Specialized Stumpjumper, Camber & any other models specifying 197 x 48mm or 198 x 51mm)
    • 7.875 x 2.25
    • 8.50 x 2.50
    • Specialized Enduro (2.125-2.25" stroke - note that some 2013 model 26" Enduros use an 8.5x2.5 LV sleeve and will require a standard 8.5x2.5 Large Diameter Corset to match).
    • Trek Fuel EX DRCV
    • Trek Remedy DRCV
    • Trek Slash DRCV

    Note: Small Diameter and Large Diameter refer to the shock's eyelet size where the air can threads in, not the air can's volume or body diameter.

    • Float CTD (Small Diameter and Large Diameter eyelets)
    • Float X (all are Large Diameter)
    • Float R/RP/RP2/RP23 (all are Small Diameter)
    • Float Triad (all are Small Diameter)
    • DHX Air (all are Small Diameter)
    • Float Autosag models on Specialized Stumpjumpers (all are small diameter).

     Not sure whether you have a Large Diameter or Small Diameter eyelet shock? The shock on the left has the large diameter eyelet, the other two are small diameter.

    Fitment note: Not every frame has sufficient clearance for a Corset air sleeve - this may include certain Specialized frames in certain sizes, we have not tried every combination! If there is ANY doubt whatsoever as to whether the Corset will fit, assemble the shock without air in it, mount it to the bike and cycle it slowly/gently through its travel. If it contacts the frame anywhere, don't ride it - just remove it, make sure it's undamaged and send it back for a full refund (minus shipping) along with the details of the make, model, year and frame size of your bike so that we can update our fitment database.
