Review on 🚲 LotFancy 2-Pack 700x23c/25c Bike Tubes, 42mm Presta Valve, 700c Bike Tire Tubes for Mountain Bike, Cruiser, Kids Bike, including 2 Nylon Plastic Tire Levers by Jonathan Suarez

Most tubes I've used that come with new quality bikes weigh between 750 and 100 grams. Each of these tubes weighs 128 grams which means more weight resistance when turning if you're into sprints and the like. and want to mount light wheels or shell out a lot of money for a light bike. Owners of such machines regularly check the tire pressure. A person who trades speed for light weight will stay away from these cameras. On the other hand, if you're an occasional recreational rider, these chambers will be fine and should hold air longer than normal for you. They look fairly well constructed, and my samples didn't have the significant burrs on the molding that sometimes cause problems with air retention marks if not carefully trimmed away. If storage space under the seat is limited, be aware that one of these tubes will take up significantly more storage space than a tube weighing less than 100g. Bear this in mind if you carry one of these tubes in your underseat bag and use one on the bike. They add two ounces, which can be avoided with lighter branded tubes.
