WTB

The WTB NanoAir 700c TPU Road/Gravel tube is a decent tube. I bought 2 of them along with 2 Vittoria Zaffiro Pro Graphene 2.0 tires. One of them has probably over 1000 miles on it. And it holds air really well. I don't think I've had to add any ever since I put it on the bike. The other one got 2 pinch punctures and another puncture the first ride out and all at the same time. I tried patching the punctures. But, I couldn't get it to hold air. Which was really disappointing to me. Because it didn't hurt the tire at all, and there were no punctures in the tire. But, to be totally honest, I plowed down a chip seal road that has some really bad spots in it. So I'm not surprised that it may have gotten one pinch puncture. But, the other one and the other puncture was an unpleasant surprise. I'm probably going to get a few more for spares for my other bikes. Because they don't take up much space in my seat bags. And I have a tendency to also get a lot of punctures on my gravel bike. And I occasionally get punctures on my other bikes if/when I'm being careless.

Bought some of these tires for my gravel and single-speed bikes. On WTB and DT Swiss hoops, mounting them was easy-peasy and they are set-up tubeless with Orange Seal endurance.

Ride quality on pavement and hardpack

dirt/gravel is good. They feel like less effort is required to keep them moving with the tread center slick.

Not sure if the Vulpine S better or worse than Vittoria T30 Terrene's. Right now, I'm leaning towards the WTB's are less ideal than the T30's.

Though I haven't actually used this WTB TPU tube on a wheel yet, I've been carrying it as a spare in my bike's saddlebag, and at least for that purpose, I think it's great. This TPU tube can fold up into a very small shape, and it feels very lightweight as well, compared to the traditional butyl tubes.

Additionally, the tube's packaging includes a couple of patches and alcohol wipes for repairing punctures, if that would ever be needed.

I have these TPU tubes on my gravel bike - Trek Checkpoint, DT Swiss Wheels, Schwalbe G-ONE RS 700c X 45mm. I inflate these to 30 PSI (I'm 165 lb). No issues with pinching the tube. Rolling resistance is really good compared to a butyl tube. I stay away from Tubeless because I don't want to deal with the mess. Furthermore, I have only ride gravel twice a week only in the winters (winter training in Vancouver, Canada). In the spring and summer, I ride my road bike. So, the gravel bike will be stationary for 8 months a year. So, it does not make any sense to set the Schwalbe G-ONE RS as tubeless - i.e. I will end up changing the sealant once a year - or 20 rides!! Also, I never loose air. There is 30 PSI in the tire for 2 to 3 weeks!!
