VeloTubes 700C X (18/25, 28/34, 35/43) Road & Gravel Bike Inner Tubes 48mm Presta Valve Bicycle Tubes, Pack of 6

I ride a gravel bike on both streets and trails, especially the Erie Canal trail in Western New York. I have two sets of rims, one with smooth tread road tires (32mm) and one with knobbier gravel tires (35mm). I use these tubes for both and have not been disappointed in their durability. I can easily get a full season on a pair, and sometimes I can extend this to two seasons. Highly recommended, especially for the value conscious.

Reasonable pricing. No flats yet. Now that I have a case, they will probably sit on the shelf.

I came across since since one of my riding buddy shared it when these went on sale. I have comfortably installed once and have another one in my saddle bag for backup. Few observations :-- Easy to install- I inflated these before installing and did not notice any abnormalities as others reported.- I was able to inflate to 100 psi on my rear road bike tire and have been riding it for a month now.I will report back if I observe something new worth sharing. For now happy riding!**UPDATE 07/02/2019**I used another tube from the set which I got and this one didn't even last a day and had a puncture. Out of the 3 that I used, I only faced issue with this one. I patched it up for now. We will see how that goes.**If you find my review useful then please click the 'Yes' in helpful.

Everything was as expected , good seller!

No to shabby!

I seldom write reviews on Amazon unless something is very good or very bad. Unfortunately, these fall into the later category. Of the three tubes I've used, all have gone flat and the hole is near the same place, on the outside of the tube (where it contacts the tire) near where the valve stem is. I've checked thoroughly for something in the tire that could be causing it but there's nothing there. As other reviewers have noted, these leaks seem to be in the same place. There must be a manufacturing problem. I've thrown out the other three tubes because I can't trust them. I had to withdraw from a race last weekend because of these tubes. Find a better quality tube!

good product hopefully, good price

Received earlier than expected. Product is, as described. Installed two immediately, and been holding 100psi for a couple days now. I’m am happy with my purchase.

Good quality and fast shipping

Can never have too many spares

Got 3 punctures on the same bike, item is defective and puncture always occur close to valve! DO NOT BUY IT - got better more durable product to save your time!UPDATED: got another 2 repairs for neighbours using this tube - 2 of 2 has been back with puncture!
