You have a fancy $3000 bike and you are still doing the pinch test on your tires. Don’t get me wrong there’s nothing wrong with the pinch test but you need to invest in a pump that will give you the exact tire pressure reading. The Topeak JoeBlow Pro takes the guess work out of inflating your tires so that every time you take that rig out that it’s going to be consistent and possibly prevent a flat from over or under inflating.
