Stripping down my Lapierre zesty carbon frame for B&B replacement I noticed a gouge right around the bottom bracket of the frame - it looks like something has gotten stuck beneath granny ring and has been scoring the carbon with every revolution of the crank. The gouge is about 1mm deep and 1.5mm wide and I'm obviously concerned and now not keen to knock out the pressfit bb cup in case the frame breaks.
Any advice as to how to deal with this ? I'm guessing as its carbon it can be professionally repaired , but would like to avoid massive expense if at all possible. Is this damage terminal for the frame , or is there enough thickness in the carbon bottom bracket shell not to be too concerned?
