Subject: Track hubsDear Mr. Brown,
we couldn't determine the exact cause for the failure of that hub, therefore we replaced it under our warranty terms; I can confirm this type of failure is an extremely rare occurrence. However our "track" hubs are not intended and haven't been tested for road use. We weren't aware of this potential misuse and are now adding a "WARNING" sheet into the packaging.
The stresses a hub is subject to vary greatly depending on riding conditions and style, weight of the rider, type and geometry of the frame, construction of the wheel and parts used, quality of the pavement, dimension and quality of the tire etc. Common sense and sound judgement are always helpful in determining if a particular situation is or is not riskier than what is commonly accepted.
I definitely recommend to use "track" hubs exclusively in the velodrome. Please do not sell them for road use. Road use can certainly be considered "abuse" or "misuse", and the fact that Campagnolo has always been quite tolerant in the enforcement of its warranty policies and has always erred on the side of the customer shouldn't encourage wrong habits.
Thank you and best regards,
Mario Zolin
