A common problem with carbon is over-tightening. Here I am rebuilding a deep crack. Its important to ensure all layers are exposed to build a strong repair.
This Fi’z’ik seat got the MTB treatment and cracked in 3 stress areas. Again you can see how brutal I get in clearing damaged areas for structural repairs that could cause direct injury. I don’t always take these on for legal reasons.
They are now successfully back in the field were they belong and so far no returns!
