WTB

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 am running these on a Trek Marlin 5. 100% of my riding is urban. So mostly streets, but also up and down stairs, curbs, etc. For city riding these are a great upgrade from knobbies. Much less rolling resistance, therefore faster. My one (pretty sizeable) disappointment is wet weather performance. WTB website explicitly says these tires are good for "bright and sunny or pouring rain"; however, my first time out in wet weather these tires couldn't hold on a turn and I took a pretty hard crash. To be clear, I was not riding aggressively, just taking a very standard corner. Wish they were better in the wet weather.

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!!

I am giving 5 stars for overall rating because I like it better than 2 other brands of TPU I've tried (Tubolito, Rene Herse.) Both of the other brands had one of the 2 tubes defective. WTB was easy to install. I have punctured twice however. 1st time a tiny thin wire went thru a thin, not puncture resistant tire. I don't fault the tube. I patched it successfully with one of the 2 included patches. I think it's great that they include these. The 2nd flat was caused by the same wire! I know, my stupid mistake. I did find the tiny cut, and looked for the sharp object. Did not find it until looking the 2nd time. I patched it successfully the second time. I had the 2nd patch that came with the tire, but used a Park instant patch instead. I wanted to try it to see if it worked, as some people have said it likely would. It's working.
