I love the Schwalbe tires - use them exclusively for my fifteen mile daily commute, and refer my friends to them exclusively for a great, consistent tire. I have witnessed a finish nail hitting the Green Guard protection and veering out the sidewall - all without losing air.
I have bee running road tubeless for three years now. The last set of tires were the Schwalbe One which I can not say enough good things about. Great all around tire. Purchased the Pro One after slicing the Ones on something that made a very large hole. The new Pro Ones seem to have a little better roll but all new tires seem that way to me. The reason I did not give this tire a 5 star rating is it does not hold air compared to the original. I have installed Stan's No Tube sealant what has remedied the situation. The original were run with no sealant.
I'm a big boy, 6'7 240 lbs. and it takes a lot of tire to hold me up. The Schwalbe One rolls, with a latex tube, better than any tire I have tried. Conti 4000s II tires casings give out before the tread goes, but these are staying round wo bulges so far with about a thousand miles. The biggest thing is the ultra low rolling resistance. They are amazingly fast.
I trained on Duranos all last summer. True to claims, I got almost seven thousand miles before wearing out. That said, this is a high-mileage tire, not a bullet proof commuter. Your going to get the normal occasional flat, sorry, facts of life. Buy Conti Gatorskins if you cannot deal with flats. But, if you want a high mileage training tire that rides like a PERFORMANCE tire, this is a good bet.
