From the beginning, was positive on:
- Very low rolling resistance (hard inflation assumed)
- easily
- Springs well, despite high air pressure.
After accidental passing through a glass crumbs heap (remains of a shattered car window on the road), I had a first flat tire - good can happen. But now: in a week 3 margins, in each case after driving over stretches that were not first quality, and always simple cut or stitch holes in the hose (no assembly errors, etc.). What was going on?
Research on the manufacturer's website revealed: The Citizen meets only the current minimum requirements for puncture protection, he has puncture protection class 3 of a total of 6 levels (proprietary scale; in class 1 and 2 apparently nothing is produced). Known Schwalbe products have class 5 or 6, but are significantly more expensive (and heavy - a drawback). Which means: if the tire looks a shard, it goes through a relatively high probability. Conclusion: the tire fly with me after 1500 km and be replaced by the ton better. But the low rolling resistance and ride comfort her they are just good, so more than a score.
