    Installing new rebound shaft/plunger?

    I have a replacement coming from the Cannondale tech room in a few days. My rebound shaft was frozen, I had a shop that is a far drive from here take it out for me so I could mail it to Cdale, but I was curious if it was easy enough to put back in myself when the replacement comes in.

    Anyone done it before?

    Thanks guys!

    If you want to remove the Solo Air Support you will definitely have to use the cannondale HD187 shaft clamps in order to not ruin your damper cartridge's lockout.
    The same goes for a non Solo Air DLR2/SL Lefty.
    Can you maybe take a pic to let us know which part you are exactly referring to?
    The HDTL 168 (Bullet tool) is also needed in case you remove the oil caps.....

    It's basically this, the proprietary nature of the lefty stuff is a let down, makes it hard for the home user to service. There are so few Cannondale dealers in Southern California and none of them in San Diego have the know how let alone the tools. I can't even take the entire thing off the bike to ship to Cannondale or Mendoncycles in NY.

    So I assume you ant to remove the actual rebound shaft the part that has the red knob/dial attached to it?
    If so that needs the whole unit to be dis-assembled and some specialized tools especially when putting it back together.....not that hard but with zippo experience I highly suggest you send it to Mendon.
    As far as removing the Lefty from the bike all you need for that is a 5mm allen/hex key.
    Remove the brake caliper, remove the wheel, loosen the upper and lower lefty clamp. If you have a XC3 stem unscrew the bottom cap and pull the stem/steerer out....after that you can slide the lefty off the frame.
    If you have a separate stem/steerer undo the stem and pull it off, tap on the exposed steerer tube with a rubber mallet and pull it out from the bottom, then simply remove lefty from frame.

    The plunger/shaft has already been removed by a friend and I'm waiting to get the replacement part.

    Thanks for the info! I was told you needed some special sleeve or something along those lines to insert into the head to mallet out the lefty. Is that only on Leftys newer than 2009 or something? Maybe I was misinformed.

    The lefty steerer installation tool makes things easier but is not "needed".
