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.

Heavier duty than many, less flats

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.

Bought them and no flats since, recommend. Curse against flats!!!!

I bought a 6pack of 28/34 so that I could switch my tires from 38mm to 32. The first one I took out of the package already had a leak (long cut). The second one sprung a leak as I tried to put it on the rim (small hole). I triple checked the rim for abrasive things, and the tires were brand new. I didn't use anything sharp to try to put them on. After that, I gave up and used a spare 32/45 from Bell and had no issues. I still have 4 but am not sure I want to waste my time.I guess I can give credit for being lighter weight than tubes I'm used to, but they're clearly too thin and/or poorly-made to stand up to basic handling. I don't even want to know how they perform on the mildest of bumpy/debris-filled roads, glad I didn't find out in the middle of a ride.

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

The tubes are fine but not of the best quality. My first tube made it about 15 miles then split down the seam. I’m on my 2nd now.The tubes tend to be out of circular and cause a pronounced lumpiness that can cause the tire to rub against your frame if you run very tight tolerances.The tubes feel fully inflated at 55~ psi which is odd as comparable tubes from my local bike shop for this very wheel size easily hold 100psi. Tubes fill out the tire but maybe the inner diameter of the tube is smaller than my normal tubes.Again: tubes are fine just cheap. I will not buy again and will purchase better quality from local bike shops.

I've been riding my road bikes for many years now with the same old ritual, pumping up the tires with prestatubes 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.
