WTBNanoAir 29 Inch TPU MTB Tube(Return to Product Page)

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 bought 6 of these. 3 have worked perfectly for a seasons worth of rides. 2 failed immediately. 1 lasted a single ride. The patches that come with are not worth the effort.
