disappointing

- Jan 10 February 2026

no, have to check tyre pressure every 5 days. hope it is not necessary with the other tyres.

Pros & Cons

after 5 days on pumping, pressure too low.

Always good choice and durable at this price.

- Emile 23 April 2025

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.

Pros & Cons

Easy mounting
Easy pumping with presta
Fits perfectly on 27.5 inch

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
Quick leak
