Looking at it, I would say it's pretty shakey. The top tube is not under much stress, and many people have ridden with dented top tubes for years - no problem. The difference is that once CF is fractured, it can easily propagate a crack all the way around the tube. I agree with the suggestion to do a pressure probe - if you can flex this, then it's toast. Rideable, yes, but when you hit that potole or your handlebar swings around and whacks the frame, the tube could easily come apart. CF is a great material, but if this were metal, you would likely only have a dent and not be the least bit worried about it. Everything has a tradeoff.Lifelover said:I don't really have answer for you but I'm curious to know if you can feel any extra flex/give in that area. I would give it a thorough testing with the hands and thumbs first. If you feel any deflection that you don't feel a few inches away than don't even consider it.

Thousands of $'s and a fall in the garage...poof!
