These tires were recommend for the style of riding I do. They certainly have proven themselves worthy of the price. The tread allows to bite in when needed in the gravel with great stability. I was doubtful of their handling on pavement but quickly changed my mind on the first steep paved curvy 10 mile down hill I was blessed with at the end of a long ride. Holy cow did they way out perform anything I've ridden in the past. Absolutely love these tires. Maxxis wins again.
So I'm an old guy (72) been riding and racing since I was a teen. So for quite a while anyway. These are the first TPU tubes I've ever run on my bikes. I like them, it's only been a couple months but they're lighter and I think maybe roll faster than butyl tubes. I've had no flats and no problems with the valve stems working with the stem extenders my wheels require. I'd recommend them.
Yesterday I was riding on the I-205 MUP, which is covered in gravel, trash, and broken glass. Somehow I managed to get two long slashes in my sidewall down to the casing. The tire is done, but this got me home.
Also, it is injectable.
