Hey Don and fellow iBOB's, This is quite a timely post! I was shopping online for Michelin Pro4 Endurance 700x28 tires this morning. The 28mm Endurance has been out for a while, but there's not much user info or reviews of them available online. My main question is actual size of the 700x28 labelled tire. Can you provide some insight on that?
I've been running the 700x25 Pro4 Service Course, which measures considerably bigger (I measure just under 27mm wide on my Open Pro rims). Hopefully the 700x28 Endurance are also bigger than marked. But by how much?? Here's a very interesting write-up of the Pro4 Endurance V2 tire on BicycleRollingResistance.com: http://www.bicyclerollingresistance.com/road-bike-reviews/michelin-pro-4-endurance-v2-2015 The reviewer measured the Pro4 Endurance V2 700x25 at 28 mm wide -- seriously oversized. Note that the Endurance model has thicker tread than the Service Course, as well as a bead to bead breaker layer for flat protection on both the tread and sidewall. This is not a fragile racing tire, yet it scores extremely well in the referenced rolling resistance tests. Another tire I'm very interested in is the Continental GP4000S II in the largest 700x28 size. BicycleRollingResistance.com measured this tire at a whopping 31mm wide and it appears to garner even lower rolling resistance scores in their testing, though it also appears to be less long lived and have less protection than the Pro4 Endurance. Anyone running the Conti GP4000S II in 700x28? Patrick's experience with Pro4 Service Course and Elk Pass tires is interesting, but perhaps not a very "apples to apples" comparison. As he stated, his Pro4 SC's (which I suspect were the original V1 model, which had higher rolling resistance than the more substantial V2 Endurance) measured a dainty 22mm wide, while the Compass Elk Pass tires measured a much more girthy 28mm (though far from the marked 32mm size). Anyone else with firsthand user experience with the big 700x28 versions of the Pro4 Endurance or GP4000S II? -Jack K.
