Yes it will, but only in a good way. And that’s also what makes aluminium such a great material – each cycling journey will add a patina of use and earn the odd distinctive scar but without impacting strength or structure. We like to think we look better with age.
Of course, no material is indestructible and there is always a balance to be struck between strength and weight. If a panel is breached due to, for instance, wilful neglect on the part of a baggage handler then it would not spell the end for your box – panel repair/replacement is straightforward and supported by the factory.
Our experience is that a Buxumbox can take far more abuse than moulded plastic or semi-rigid boxes (and is repairable too!)
