Hi Burners So long story short, out for a road ride on my 2016 Giant Defy Advanced, in which I managed to get a large self taping roofing screw jammed in the rear tire. What resulted is a blown out tire, and as I still coasted along a banging and knocking sound. Upon inspection the noise was coming from the nail & chain stay/BB junction, it was whacking the frame on the way past. Results posted below. Despite being pissed at how retarded this incident was, was wondering what peoples opinion are on this? Cause for concern? Giving it a close inspection, I'm hoping its just superficial in that it took away the paint and undercoat. I can't feel any delaminated carbon or broken fibres running my hand on it. Have emailed giant and waiting for a reply. If superficial was thinking of cleaning and putting some clear coat over to avoid any potential corrosion and keeping a close eye on it. Praying this isn't a write-off. Saved forever to get this beast, and i don't like the new models colours. Its a shallow world. Thanks folks!
