I had two flats over 4000 miles on my road bike on armadillos. Once was an ultra tiny sliver of metal wire. Once was the sidewall blowing out. :shrug: Tires are a lottery. I say Schwalbe is better because I've had similar flat experiences and the schwalbe has reflector sidewalls where the 'dillos have ugly red sidewalls. Riding a bike = flats. Its a good reason never to buy a nexus rear hub
