my wife and I tried going for a bike ride yesterday but we discovered that her front tire has a leak somewhere. She's ridden her bike less than a dozen times . my question is, can I just pop the front tire off and take it in to the bike shop and have them fix it, or do I need to bring the entire bike? I know this may sound like a dumb question but my guess is that if the rims need truing or if the tire needs replacing they can do it without the bike, right?
