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.

Great tube

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.

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.

I've been riding my road bikes for many years now with the same old ritual, pumping up the tires with presta tubes just before a ride. Now with the Velo tubes do I have to put any air in them, they just hold a good pressure. Maybe after 3 or 4 weeks you may have to put a few pumps in them. My riding friend needed a tube for one of our rides and I gave him a couple and he is amazed. This is the second 6 pack I ordered within a year now, simply because my friend wanted an extra set. You will not be disappointed with them.

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!

I have bought this 6 pack of tubes for a few years now and had never had any failures. But on my last order, 3 out of 6 of the tubes I had received were found to be defective upon inflation, I was frustrated and left a negative review. This seller (Eric) went out of his way to send my a new set of tubes with a hand written apology and ensured me that my experience was a very isolated incident, and based on my experience that's true: I have ordered around 10 or so 6 packs for use by myself and others and really hadn't had issues. I didn't ask the seller to send me replacement tubes or even let him know they had failed, he took the initiative himself. I think that speaks volumes for this seller and have no problem reciprocating with a positive review because I am confident that buyer will get a great value and be treated fairly in the rare event of a defective batch. 5 Stars Forever
