Review on CH. A3 AIRSTOP 35/47X622/635 ST 34mm: Premium Tire Inner Tube for Enhanced Cycling Performance by Dustin Miller

After a couple of punctures - all on paved bike paths, no terrain - I bought a set of Michelin Protec tires and these tubes. ZERO problems in almost 3000 miles since then. Last fall I wore the tires and replaced them with new inner tubes. It was October; I didn't need to refill air, now 6 months later! I ride several times a week; mostly paved, with some light gravel/packed earth here and there, but any component that doesn't cause problems wins in my book.
