Good Quality ,cheap , job done
Came with hardware good thick tube doesn’t leak but the stem could be higher quality for the thickness. It is a super heavy tube fyi obviously there will be trade off for durability and I beat the soul of of my tubes, they hold up just fine next to my Michelin 3mm

Valve stems held up on these for me but I have a Tusk rim lock. Anyways I think they get dry around 4 months or riding. And pinch easy on lower air pressure. I’m on my third one.

Right tube at the right price.
Nice tube. A little extra thickness but not manageable bulk or stiffness when installing. Valve stem slightly longer than OEM ~ I like it. 180/90 - 18
