Replaced Conti 4 Seasons with these. Much quieter. Holds pavement well. About 400 miles thus far over rough pavement, country paved roads with lots of extra lose gravel on them, occasional sections (half mile to mile) of gravelcaliche. Holding up very well, no issues. No problems getting on my Zipp wheels. Like the block lettering as well. Running 23mm and possibly a bit harder than previous Vittoria tires, but they were not the same flat protection at all. Going to move up to 25mm after these wear out.
Will not order again-very difficult to mount on my 700 Velocity A-23 rim. It did not seat well either-I finally got it to seat properly by pumping the tire up to 160 PSI and let it set overnight-magically it was seated the next morning.
I purchased these for my usual daily commuter bike, to replace some Michelin Krylion tires that I still had in my stash. (I have decided stashing tires for long periods of time after purchasing a bunch is not a good idea but that's a different problem.) The Krylion is now the Michelin ProRace 4 Endurance, I guess - I wish Michelin would stop changing up the names of these. Anyway, I got confused and thought the Endurance tires were being replaced by these Power tires.
I don't regret buying these too much since I expect them to last well enough, but as another reviewer wrote, I don't look forward to making a roadside tire change when one of these flats, they were not easy to get on the rim. This surprised me, since I have used various versions of Michelin 700 x 23 and 700 x 23 road clinchers since I started commuting on road bike going back to ProRace2 tires and I don't recall having this much trouble with any others. I would have thought they were wire beaded, but they came folded up, so that isn't the deal. Odd.
Love these tires on my NYC street riding Cannondale Caad12 Durace...I have the 700x28 with the Michelin a2 airstop tubes, which makes for a nice plush ride with much better grip !
They have been on for a whole season and not 1 flat !
I recommend these tires & tubes !!!
Im a casual street rider & occasional velodrome rider in Queens,NY...I like these Michelins along with the Michelin tubes, nice grip confident riding and tubes hold pressure for days...
