I was sceptical about carbon too Hora so decided to put it to the test about 18 months ago. I built a carbon Enduro with as much carbon as you could throw at it and spent the last 18 months trying to break it. Spec include havoc carbon bars, sixc carbon crank, easton carbon wheels…..only thing I managed to break was the front haven when I took it for a blast down Aston hill. Other than that its been perfect and hasnt skipped a beat. Compared to the Aluminium Enduro I had previous to that for a short while, the carbon is a stiffer frame which I find helps hold lines when on the ragged edge. The fact is a few hundred grammes lighter wasnt much of an issue TBH. Certainly no trouble trusting carbon in my mind now.
Here’s the wheel which failed safely and continued to hold air (tubeless)
and the bike…looking a bit tatty now but still in one piece (this is with the havoc wheels I used whils the havens were away being replaced under warranty)
