I don’t think so. I think they’re better but it’s a very small percentage in terms of times. Close to latex IIRC.
They are supposed to bring watt savings, which could mean faster speeds at the same effort, or the same speed with less effort. I have noticed it, especially at higher speed.
And the rotational weight savings seems to also make a difference in climbs. Easier to push up climbs, and still faster than before.
I do believe there is a solid benefit in comfort compared to typical butyl with supple tires but that’s pretty subjective.
Yes! Even with more pressure (they felt way too squishy at the same pressure I was running before), they are still more comfortable.
The only downside in my mind is they’re slightly loud. I’m very happy with them, and recently had a puncture and was happy that the patch seems to hold.
I love the sound! LOL It's different, and slightly unnerving, but pretty cool.
I'm not sure if I'll be putting TPU tubes in my old MTB, which I ride all year. If the ones in my gravel bike hold out well until November, I may just go for it!
Average overall speeds are up, but not by that amount since it's urban riding with lots of things bringing that number down (stop signs, red lights, pedestrians on shared paths, etc.)
But for segments where I can just go, speeds are considerably faster.
