Review: 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
Review: 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
