I dont want to speak for the company but they have helped me so many times on the fly. I'm sure they could change the tube for you while you wait. They are very helpful and a great bunch.
Sorry we're getting back to you so late Dennis (unfortunately it's a little difficult for us to get on Google everyday.) If you haven't already, please stop by and we'll take care of you right away. Just let us know you are on bike as we do our very best to take care of bike commuters ASAP. (P.S. - if you are unable to call, Facebook messenger is your next best bet.)
Thanks! Your answer is awaiting moderation.
