This is a good 'middle of the road' tube, you can get more expensive ones, but this one is plenty tough for new england rocks and roots unless you're a serious racer. The price of this tube also makes it a good value.
...but not for off road. This tube is not very thick, like a Bridgestone Ultra Heavy duty. I ended up replacing it witha Bridgestone after the valve stem was torn while running 18 PSI! Again, it would be OK for the street, but find something better for real off-roading.
