1 Pack or 2 Pack - Bike Tube, Presta Valve 700c x 28-35, (27x1-1/8 to 1-1/4), 32mm Presta Valve, Bicycle Inner Tube, Sunlite

I’ve been using these tubes for three years in two bikes. They are very durable. I had one tube get nicked by some glass and I found out after a year of riding when it finally developed a slow leak (700c x 32).This has a short stem, which is perfect for my bike. I hate 50mm stems sticking out of my wheels.Side note: I always pressure test new tubes. Manufacturing faults can and do happen. I pump a new tube with some air, not too much, and then wait for several hours to see if they’re good.

I've been buying this brand on Amazon for a few years. Tubes are always quality. Also, I like that the stems unscrew so I can add Stan's for leakstop (California goatheads!).

So far so good.

Good tubes, reasonably priced.

Was excited about these because they come with a reasonable, old school valve stem of only 32mm.Only problem is that they don't seem too durable. I replaced the wheel and the tube must have gotten pinched and tube was toast.So, my review is as follows:Valve stem length: 5 stars !!!Durability: 2.5 stars

They leak overnight. I believe it's poorly made valve in the stems. They'll probably last my bike ride, but constantly pumping them up every day is going to get old.

I am a novice bike rider, but it was not difficult to install and did not take long either. The shipping came pretty quick, hence I bought this to arrive first for my main bike and the other sets I bought to arrive later.

I took one 4-mile ride to work and my tube suddenly deflated, while it was on my bike rack. While I understand that one can argue various factors to contribute to the flat, such as terrain, bad riding tenancies, installation, etc... I can assure you that it was none of the above. I take great care in my bike and take pride in it. I carefully installed the tube put the proper psi as indicated on my tire (116psi) and closed the stem securely. I have no words as to why this tube deflated, except for it's durability. I don't think I will be buying more of these. Please don't waste your time with these and look elsewhere.
