Is this Carbon Frame Cracked?
Would you guys/gals still ride this frame?
I have had this carbon frame since this spring and have been happy with it. I took a nasty fall and hit a tree a couple of weeks ago. There was no damage from the actual impact with tree. However, I failed to notice that the new straight handle bars puts the shifter and brake levers in a position to hit the top tube when completely turned.
This doesn't look like a complete crack to me but I don't know if it's still safe to ride. You can feel the difference when you put your finger over it.
Would you still ride this frame?

looks like that is in the actual carbon layer to me. You should have your shop check it out.

Looks like a crack and I wouldn't ride it. Take it in to have it looked at or tap it with a coin to see if the tube it sounds "dead" in that area of the tube.

Are you saying the bike did not hit the tree but this is from the brakes and shifters hitting the top tube? IF that is the case, I seriously doubt it is cracked. Honestly, that looks like the clear coat is cracked from the brake levers. What kind of bike is this?

That is correct. My body took the majority of the blow of the head on collision with the tree. The mark on the top tube is from the levers when the bars were turned more than 90 degrees. I had to use an allen wrench to loosen the levers to get the handle bars back to the normal position.
-
Sure looks cracked to me, and no I wouldn't ride it until a qualified person checks it out and okay's it to ride.
-
Looks cracked and next time leave the levers loose so if they do hit, the can move to minimize the impact.
No, YOU don't understand. You're making an ass of yourself for all of eternity.

LBS is most likely only qualified to sell you a new bike. Have a carbon expert look at it.
-
Looks cracked to me, you should be able to easily feel if it feels less rigid than the rest of the frame - normally feels spongy when cracked/can easily be pushed in with your thumb. Wouldn't ride it until I determined the safety of it, not worth the risk to you IMHO. Is that a Chinese special?
-
To me it looks like the clear coat has been scraped off and that is all.

Looks like it is

Contact Calfee, they repair carbon frames and would be able to offer their expertise or send the image to the mfg for their take, hopefully you are under warranty. If not:

Let us know what the verdict is.

Warranty doesn't cover impacts. Maybe crash replacement program. I put pieces of Shelter in that area for protection.
No, YOU don't understand. You're making an ass of yourself for all of eternity.

You can use a bit sandpaper to release the painting to see if its actually broken underneath the paint.

no need to worry. looks like the clear is damaged not the actual carbon

Sand it down past the paint, you are looking for severed fibers, from your photo I would guess paint damage.

This. A tap test will quickly tell you if it is delaminated in the area of the indication. It won't necessarily feel "soft" as someone mentioned.

Looks compromised. Call Calfee. It should only be $200 to get it fixed as long as you don't ride it longer and make it fail in a larger area.

I would not touch the surface with sandpaper. Get it looked at first and don't screw up any evidence for the repairer or inspection.
