Works great, seems high quality. I installed it with a new tire and it worked great.

I keep a stock of these (and the 21″ fronts) for dualsports and adventure bikes with larger rear tires.These have worked great on several long hauls and over 10k-mi trips comprised of harderoffroad and many road miles. Durable at a reasonable price. Beware that these are thin enough however, to pinch if you’re rushing install.These are slightly heavier than the stock Pirelli tubes my T7 and FE 350 came with, though there is a heavier HD version that isn’t too insane.FYI part numbers for 21/18″ SD and HD tubes:18″Heavy:T20057Standard:T2006421″HeavyT20076StandardT20078
