What is RM Cash
Raymond in WY
I like the heavier duty tubes, but I keep this one as a spare.
Zach in UT
Much thicker than i expected but it works great.
Josh in WA
I love these tubes. They hold up very well and I have yet to get a pinch flat running them for the 3+ years i have used them. These things are tough
