Hi guys,
need some input.
I recently noticed that my carbon steerer looks like its pinched (torqued it 4nm)
I have yet to bring it to my LBS but it definately doesnt look like its cracked.

Do u think its safe to ride or should i get a new fork?

Hard to say, but that looks cracked up at the top. If there is a sharp ridge that you can feel when you run your finger across it then you better take it in to have it looked at.

Cracks usually run in a jagged pattern where scratches are usually less errant....looks like u have a crack. EM3

Where there is a crack there is often a delamination, don't use it until it has been professionally inspected.

If you don't see any irregularity from the inside, then some epoxy and a 2"-long aluminum tube (go to home depot and get a pipe in the 22-24mm range) will easily fix it. I did it on a Nag Dream HP and worked just fine. Only complication was expander plug was replaced by a star fangled nut.

If u c a crack from the inside, then it's gone.

you epoxy the crap out of it to the inside of the steerer after you have removed the compression plug. The forks that cervelo has (3T) do this also to reinforce the steerer.

Make a little mark so you can check if it gets worse . Better to be safe .

pinch is a precursor to a crack. use carbon paste and slightly less torque. like others have said, i would try to epoxy it to smooth out the sharp pinch...sand it smooth. check your stem.
