Was put off cf when this happened (to be fair the chain stay was pretty dinged as well)
Correct me if I’m wrong, but that looks suspiciously still in one piece. So your issue is that you have a big impact of some sort (might be more useful with a little context), and a cf frame gets damaged?
Well the stay is cracked all the way round and what you can see is splintered and deliminated through its depth. The chain stay is Al and pretty bent out of shape and this was a point stress break on what i would assume is one of the structurally weaker points of the cf. Large lateral loading on a single point. Oh my roadie has plenty of cf so i should have qualified the statement with “I was put off having cf on my mtbs whenthis happened”
