So after some fiddling around being careful not to squeeze the tpu’s i changed my schwalbe with normal inner tubes to conti’d with tpu. Difference in weight is around 314 grams total less.
First ride, absolutely less comfortable which i knew already. But it is a bit more uncomfortable than i thought with 4 bars.
The ride is a bit lighter but not as much as i expected it to be. I do have to ride more often to be sure though. I tried with zero assistance and with. I hoped without to be much better but it is nowhere as light as a 16” c line with 2 speed. I have to see whether the change of less comfort is worth it for me. Another option is schwalbe with tpu. The difference in the tires is less than i thought. 49 grams per tire.
Tpu versus normal is 41 vs 149grams. So tpu change alone is about 200 grams which is a lot.
