Got these stock on my Steamroller. Nicest tyre I've ridden, probably because of the lack of Kevlar. About 1000km on them so far with a minimal wear and no flats. I did a few skids on them early on and the back looked like would self-destruct if I kept it up so that is certainly not what they are good for. I'll think I'll just use my brake and continue to watch what I roll over.

I run 120 psi and I'm 60kgs.
