A quality product & delivered swiftly by Cyclop. Carrying it as a ‘spare' can be quite a task, as the fold isn’t compact due to the fluid inside. It takes a lot of space in the saddle bag. I replaced my original tubes with these & the originals have gone into the saddle bag as (compactly folded) spares. Overall, satisfied with the performance so far!
