Not my inner tube.

- Robert 16 October 2022

After wanting to get rid of tubeless I bought these. After a few short rides on the Levo, did a slightly longer one (44km). On the way back end punctured. Next morning front was flat. Not the best quality it seems to me. Can't be a coincidence.

Pros & Cons

Easy to put on.
Seems light

super tyre lasts long (I hope)

- Raymond 31 July 2020

Problem is, of course, that I have to assess this purchase. But yes, punctures within two weeks obviously don't happen. My previous inner tube (also schwalbe) lasted longer than its outer tyre (and that was several years, > 3, don't ask me how many, and the bike was used almost every day). So, yes, fine product. will definitely buy again. R
