Well made tube! The valve I really like, because my previous purchase from another company the valve threading doesn't even let the cap go fully on before the rubber tubing stops the cap. Compared to the valve your tub has. It goes all the way to the rim and is made out of a rust proof material it seems. Throughly enjoy my purchase.
I've taken this tire through a good 300 miles in the month or so that I have had them, and I have yet to be let down. They have been ridden through the ruts and cracks of Western mass, the glass and potholes of Boston, and I have been bunny hopping them to my hearts content while at speed. 0 punctures to date the grip through wet corners has also not let me down, 0 slips, very confidence inspiring. If your on the wall about these tires, pull the trigger. I don't think you will regret it.
Top notch tire. Did a spring classic with about 13 of the route on gravel and dirt roads and the tires held up through the whole route. Hit some serious ruts, bumps and potholes and the tire never quit. My buddy and I both rode these tires and neither of us had a problem.
