Has anyone else had problems with Neuron Tubes rusting. Just having my 2nd tube replaced on my 10 year old steel frame. The first one was mostly my error for not wiping off sweat after rides but 2nd one was a surprise. I live close to the TX coast so heat and humidity are the norm but I have had other steel frames and not had this problem. Also teh rust is not in the usual places around braze-ons and such and I don't have "toxic" sweat that kills bikes and parts. Any guesses?
