Always good choice and durable at this price.

Replace only with Schwalbe inner tubes. In my experience, they don't puncture easily. Can take bark some blows from Jumps and unexpected root stumps on the track. Fit well in my 57-584 (27.5x2.25-650B) outer tyres.

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.
