I've been using both the 23mm and 25mm previous-generation P Zero Velo tyres. plus the new generation 24mm version. I do find them pretty fast and comfy. Thousands of miles on them this year, one puncture from a tack I ran over, then another when I clipped a golf ball sized rock while going through some roadworks (tore a small hole in the sidewall). I did get a flat spot on one tyre that wore to the carcass. That would have blown big time if I'd tried another ride on it!

But all in all, I do rate them. 🙂

If you're after a super puncture resistant tyre, or a tyre that lasts for a huge number of miles, there are better choices. But as a fast road tyre, they're pretty ace.

One little thing I noticed. On my wide-ish rims, the old 23mm tyre measured up wider than the new-generation 24mm tyre.
