Problem with fork upgrade - fear of carbon steerers(4 posts)

Problem with fork upgrade - fear of carbon steerersAlexR

Considering I won't clamp my Kestel by the top tube in the workstand, I have a few reservations about clamping a stem on a carbon steerer.

These fears have no grounding in fact or experience, but they're pushing me toward the Ouzo Comp with an aluminum steerer. I'm not worried about the strength of the material, 6k good hard miles on the kestrel have erased those concerns. I'm worried that my gorilla-fisted manhandling will destroy this bugger the first time I put the 6mm allen to the stem bolts.

Anybody out there hamfist a carbon steerer into the junkbin?

I'm about to trust the two of us to a carbon steerer on a Calfee Tetra Tetra Tandem. I don't think they'd risk their reputations (Calfee and AME) on our lives if they didn't totally believe in the strength and reliability of their product.

Hmmm, actually it's a lot harder to damage the steerer with the stem - assuming you use the correct stem. The beefy work stand clamps utilize a four bar linkage and a lever handle to really apply significant clamping pressure, plus there's the whole issue of having the entire weight of the bike, plus applied forces by the mechanic to make things worse. Also, the clamp diameter doesn't necessarily match the frame daimeter.

Ultimately you will probably strip the threads for the cap screws before you do any damage to the steerer. The exception is that if you use a stem the has a wdge mechanism it can point load the steerer. if you really want to be safe use a good quality torque wrench with a 6mm hex bit when you tighten the stem and follow the torque spec, but I really don't think that this will be necessary.

consider an AME fork with a ti steerer. If you go with a carbon steerer, just be sure to get the right stem.
