For more than 15 years, Rich Sherman, store manager for in Wayzata has been helping people buy, maintain and fix their bicycles. He took a few minutes to demonstrate some key techniques for changing a bike flat on the road.
In addition to the basics of removing the wheel, tire and tube, Sherman emphasized how important it is to carry a bike repair kit with you while biking, especially a replacement inner tube.
During the replacement process, it is critical to examine the inside of your tire for objects or damage, as this can cause the replaced tube to flatten immediately. Examining the wheel after reinserting the inner tube for areas where the tube is bulging out from the tire can also save you from repeating the repair in a short time. Filling the tube to the correct air pressure will also protect the new tube and tire.

Sherman suggested that an inexperienced bicyclist can repair a tire in around 20 minutes, while a more advanced biker can do this in five minutes.
