Diamondback 700x35/45 48mm Threaded Presta Valve Bicycle 0.9mm Thick Tube- Black (new)

Every cyclist, including casual commuters, serious mountain bikers, and dedicated roadies, should have a stock of tubes built up in his or her bike closet. After all, no matter how hard we try to avoid getting a flat tire, it’s a fact of cycling life that you will end up with one someday. We’re fans of keeping a few spares within easy reach so you never end up leaving on a ride without one. It saves time, money, and AAA from making a roadside assist because you were out of tubes before you left the house. And buying in bulk when tubes are on sale can ultimately save you a few bucks; despite their simplicity and small size, they can wreck your monthly budget if you have a few blowouts.
