Carbon flex pivot "air moulding" (aka mouldless process)

Our friend David got broken his Yeti 575 frame. One of the carbon flex pivots showed a deep crack transversal to the seatstay, only a thin carbon layer remained intact but it was very close to split apart the pivot. We decided to try a fast reparation via "air moulding" a new flex pivot. The process starts by cutting and preparing the original one, then a small piece of UD carbon sheet is bonded, the carbon fiber is arranged lengthwise to take the flexion stresses once in service. Some extra carbon properly layed up and the new flex pivot is refurbished and ready to be reattached to the frame.
