    Problem--Lefty Speed Carbon

    I have a little problem with my Lefty, which has been sent back to Cannondale for a rebuild, and am wondering what people think of the problem.

    Problem: At 150psi the lefty only extends 85mm instead of 110mm, and if I pull hard on the handle bars, as someone holds the wheel, the lefty will extend a couple more centimeters. At 195psi it will extend 105mm, I did this a test only, so the fork has never been ridden.

    I know another person with a Speed Carbon and they have the same problem.

    Any thoughts?

    Do you mean that the distance from tire to the crown is too short? Or are you just unable to compress the fork to it's full travel at these pressures?

    If the LBS (I'm assuming they know their stuff) sent it back to Cannondale, there must be something wrong with it and I don't think Cannondale will send it back unfixed. Let's just hope it doesn't take too long so you can ride the bike.

    Interesting.

    I've never actually measured the claimed/advertized travel on any of my Lefties.
    I'll just have to break out the tape measure when I get a chance.

    Are there different rate negative springs? Otherwise it's an air sprung fork but I don't think the negative spring can make much of a difference. Of course, I could be wrong...

    Yes there are different negative springs available.
    Std is the blue on which is pretty strong.
    The white is the weakest one.
    It's a little coil spring and it's usually this one this is repsonsible for excessive top out and other Headshok anomalies
