    lefty carbon SL rubber seal



    Hello to everyone and Merry Christmas!

    We have a problem here in GREECE the lefty fans.

    How we fit a carbon SL lefty to a scalpel frame without to strip that rubber seal which goes between the upper headset bearing and the lefty.

    The space which is leaving the lefty when goes to the bearings (before to fit the SI stem) is very little and all we succeed until now is to strip the rubber seal as also the upper bearing.

    We couldn't imagine that this little thing would be so difficult.

    Practicly we can aligh the upper lefty holder, the rubber seal and bearing so the SI stem to can goes through all these.

    Please some christmas magic light to help us here.


    Thank you

    Lube it up with grease or silicone spray....and use a small, flat screwdriver that's not too sharp and carefully push it in...that's how I did it and it took me almost 30 Min. to get it seated right the first time..... I messed up 2 seals before I finally got it right....
    Now I always keep a spare one in my tool box

    This is the only way?

    We tried and this also but the whole thing is very delicate and fragile.

    Are you sure there is not some trick? That means that every time you have to reinstall the lefty on the bike you have to go through that procedure?

    How about to skip that seal?

    try to do in this way :

    seat over the frame , as you must ride it...

    with fork in your left hand ...

    keep your left arm close to body ....

    align lefty to frame , then turn fork counterclockwise to position 7 o'clock...

    then press and fit lefty fork on position over the frame ...

    turn it clockwise to standard position...

    hope to explain well

    in this way you can find the 1-2-3 mm clearance to do work without problems

    Thank you all Guys!

    We tried the method of Cdalemaniac first and then if we couldn't we would try Eliflap's method.

    We were 2 so we greased the upper bearing and the rubber seal the one pushed the lefty up to create the space and the other just pushed slightly the seal just with the fingers and alighned in the first try.Maybe luck we don't know but 100% success

    Happy New Year to everyone

    I don't know if you can get Cannondale specific tools in Greece, but I have found their tool KT020 "ernie" to make the job of installing the XC3 stem/steerer a lot easier as you can push it up through the lower race, use it to align the rubber cap and as a guide to tap the stem down through the bearings.
