2/4 Pack Ridenow TPU Inner Tubes 700 x 18-32c Bike Tubes with 45/65/85mm Presta Valve

I haven't ridden on these too long, so I can't speak for durability, but I'd expect it to be the same. That being said, I found installing these to be easier than standard butyl tubes because of their bright color and slippery material. With 25mm wide wheels (18mm internal) and 25mm tires they went on without any tire levers. Each wheel felt a noticeably lighter after installed, as did my spare kit, which also has more room now that the butyl tube has been replaced. I'm not going to say it made a crazy difference, but my bike feels a little more nimble and responsive now. I may be wrong here, but it seems like my bike is much quieter with these tubes installed. I've never heard anyone or read anything mention that with TPU tubes, but it was one of the first things I noticed. Edit: after a 60mi ride in the Tour de Houston, they survived the rough roads flawlessly. I had no punctures even though I had the tires aired down a little for the rain. It's hard to say, but they do seem like they roll easier than my old butyl tubes, especially when going around 20mph or faster. Strong, heavy pedal strokes seem to result in less "whoosh" noise and more towards acceleration.

These tubes are lightweight compared to butyl, also marked for ease of use when installing. The tubes don’t leak any air and seem durable, I’ve ridden them once and they’re holding pressure well.

My only criticism of these tubes is the lack of thickness. Other than that I am very satisfied with these products.

I put these tubes into new Gatorskin Hardshell's last year. They hold air as well as butyl and are way lighter. The "named brand" TPU tubes are pretty expensive so I thought these might be worth a try. I am replacing the old tires after 6,000 plus miles and going to give them a new set of these tubes. They just work and I can recommend them. If you are fixing flats on you tires where you ride then I can not recommend them. No idea how you would patch them.

Very cool and light inner tubes. First time using TPU INNER TUBES. Very light and comfy

The idea is good. Lighter and more compact than butyl. However they are not there yet in terms of construction and easiness of install. I installed two on my wheels and both were pintched during install and deflated a couple minutes after installed. When I took them off and try to inflate to check where the failure was, one of them simply blew off like a ballon. Going back to the old trusted butyl. Installation is much easier and durability is light years ahead this TPU material. Because this TPU is much thinner than butyl install is very hard since it does not contour well to the tires. Returning these.

Really nice product, just as good as tubolito tubes. Make sure you fill with a little bit of air before putting on the rim. They ship the tubs as comprised as possible so fill to get its shape will help prevent install pinches.Update: Unfortunately, both tubes have popped with in a few rides. They seem to be very fragile and non repairable with the patch kit.

There are lots of negative reviews out there, but my experience is nothing but positive. I’ve been riding a month on these tubes and I think they are a smarter replacement to tubeless….cleaner and easier to use. I’ve been using them at about 85psi and they’ve lost only about 10-15lbs max in 3 weeks which I think is very good.

Excellent product

Ultra léger, compact, efficace, résistant, permet de diminuer espace et poids

180g lighter for the pair over my old 32c butyl tubes and marginally more expensive than a butyl tube of the same size.

Purchased a set of these tubs in June of 2024 and installed them on front and rear of a high end road bike. Within a month I got a flat in the front tire. Then within 2 month the rear also went flat. I am now back to regular style tubes, or may go tubeless. These are not durable, especially with how much they cost. I will not be going back to these tubes even though they did feel good and rolled well. They cannot be relied on when out on long distance club rides.

I bought the four pack. These save me 70 g per wheel compared to my Conti inner tubes. I am using these on aluminum rims, both had fresh rim tape put down - Velox on the rear, the front had Schwable. Installing the inner tubes was pretty easy, I used a mini hand pump to round them and they were easier to slide under the mounted tire then regular butyl tubes with little worry of pinching them on the tire bead. However, part of the Velox tape moved so the inner tube expanded in to a spoke hole on inflation and was ruined. After that was fixed there were no immediate problems and they held air very well and really felt excellent. I could feel a difference compared to butyl tubes with 27 mm Challenge XP tires. After about 2 weeks the rear developed a leak. I found the leak close to the valve, but about 5 mm away from the circular seam around the valve. I thought the stickers included were patches, but it turns out they look to be reinforcing for around the valve. Nevertheless, the hole would have been outside of this coverage. Nothing in the instructions mentions these valve stickers that I could see. I did see there was a tiny 2 mm overlap in the ends of the rim tape in this wheel which may have worn the hole with the small bump. So I trimmed this and installed my last tube with the valve sticker for good measure & ordered a patch kit. I hope this stands up now. The ride feel is really compliant, I think the hype is legitimate. Mainly, these are making me want to get proper tubeless rims now.Edit: I recieved a two pack today. Interesting to see that the stickers for around the valve are larger, plus they each came with 2 patches so I don't need to order any for now!
