I rode saturday in the Tour de Cure in springfield tn and the bike did fine for 29 miles and then the rear tire blew out. i just had the lbs put a new specialized armadillo on the rear 3 weeks ago. i have only rode the bike 150 miles or so since installing the new tire and tube due to me having bronchitis for the last 3-4 weeks. i have had flats before but never one just blow with no warning. i was on flat ground after just going down a little hill i went through a little gravel at the bottom but the tire blew 100 yards past the gravel. i had the tire @ 125psi and i weighed in @ 321 that morning.
any thoughts? i am going to go to the lbs tonight and see if they will warranty the tire.
