Hi guys,

I currently ride a carbon fibre LOOK 996 and am having some mechanical/ frame issues. After repairing a knock that had developed in one of the rear pivot points, it has now developed a severe creaking sound from what appears to be near the bottom bracket. Dad's a mechanical engineer by trade and we've had the entire back of the bike off with all bearings been replaced and even with the fitting of a higher spec bottom bracket. It primarily becomes vocal whilst pedalling, and very slightly when the rear suspension is under load.
