Went to ride my super commuter +7 and saw the front tire was low. Did not know if there was/is and issue with the tire. Called the show here I have just purchased this bike and was told "we have seen a lot of Trek bikes with metal fiings in the tire. Pump it up and see what happens." Huh? I just spent a lot of money on a new bike and there is an issue with the tires? I do not want to be out riding my bike with the possibility of those tires going flat.
