    Carbon steerer flexing

    I just installed a Ritchey WCS Carbon Cross fork and I can cause the steerer to flex quite a bit with not as much force as I would expect. I can make it flex in all directions (left/right, up/back, and twisting). Is this normal for carbon steerers?

    Thats never happened to me, but both my road and cross forks are the respective easton EC90 forks.

    Does the EC90 have an aluminum sleeve on the inside of the steerer, or is is 100% carbon?

    How much does the steer tube extend above the headset? 40mm of spacers is the recommended maximum for carbon.

    There is a 10mm spacer and a cable stop that acts as a 10mm spacer, as well. So in all, 20mm of spacers.

    I hear that is prone to flexing in addition to the Easton EC90x.

    I dont think that my easton has an aluminum sleeve. It dosent seem to flex, and I never get any fork shudder.

    Just for reference I weigh about 150# so I'm about average sized

    I have an EC70X, no flex, alu steerer. I suggest you take it to the shop and be safe. You don't want this to happen:

    Mine is a Ritchey, with a carbon steerer.

    What stem are you using? Could it be contributing to the flex you feel?
    It's none of my business what other people think of me.

    I test rode a Ridley CrossWind with the renowned 4ZA fork. Carbon steerer, flexed more than I thought a cross fork should.

    Most carbon steerers flex a little bit. The ones that dont have staggered bearings size (madone, SL2).

    Carbon is designed to flex in a designed direction and be stiff where needed. Have a good shop check it out.

    But its probably the nature of the beast.

    If it's flexing easily, I would assume that it's cracked. You shouldn't be able to flex it. Have it checked out.
