Repaired carbon frames -- Would you ride it?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Repaired carbon frames -- Would you ride it?

I crashed my bike not long ago on a descent; wasn't going too fast but the road was slick and the tire lost traction =/
At first glance, I didn't notice any big damage, but when I did a wipe down at home, I noticed a scratch/crack on the downtube.

I tried to examine it thoroughly to determine what it was exactly. Did the tap test with a coin and didn't notice any difference in sound.. to my untrained ears anyways. I also brought it into a carbon repair shop for assessment, and the mechanic there told me it's very unlikely a crack, but I should keep an eye on it to see if it gets bigger.

I'm still not 100% sure yet, but if this turns out to be a crack, I can get it repaired for approx $300, which doesn't seem too costly compared to replacing the whole thing. The big question is, would it be fully reliable after the repair? I really don't want to be riding a frame that may potentially snap in the middle of a high speed descent.

Would love to hear opinions from the experienced members here, or even input from members who are riding a repaired carbon frame.

I'd totally ride it after repair. 300 bucks is a good price for repair too.

Going off these photos it looks superficial to me. If you tested it, then had someone take a look at it then it's probably fine and you can use some touch up paint to fix the scrtach on the V. Just my .02.

Looks fine to me. Didn't even hurt the paint under the decal.

But yeah, I'd ride a repaired carbon frame no problem.

I would. Heck you've probably flown on aircraft with bigger cracks than that fixed. Probably not a carbon carbon fiber part unless you've flown on a Boeing 787 but cracks all the same.

Looks like a scratch to me too. But I'd ride a properly repaired carbon frame. A friend of mine got one repaired and repainted; it looked good as new and rode the same as previously.

I'd say relax and trust the carbon repair shop mechanic's advice. I highly doubt they routinely turn down legitimate work.

Thanks guys. Really hoping it's just a scratch, but don't want to get my hopes up before testing it on some easy rides.

For me it would depend who did the repair. I wouldn't trust some fly-by-night with no reputation.

Send some photos to Calfee for a quote and see if they think it needs work. They are the gold standard for carbon repair.

Good idea, I'll give that a try. Is it possible to determine whether it's a crack simply by looking at a pic though?

Agreed, Calfee or some shop with a great rep would fit the bill.

No way to say for sure, but they will have a better idea than both you, me and anyone else on this forum. Having said that, I had them repair a carbon frame that literally no shop would touch out of fear of causing additional damage; they did a fantastic job and the frame is good as new.

Glad to hear it worked out well for you coppercook62! Carbon repair is sounding like a promising option

+1 to both of these. Very minor scratch.
