I’ve been running the 55mm G One RS Pro’s on my gravel bike this year and the 40mm GR One RS Super Race on my road bike this year. I’m in Ohio where the gravel can get rough but punctures usually are not a major issue. On the gravel the RS Pro’s have been great, but you more or less forget you are on a gravel tire when you hit the road. I did a recent 1 week training camp in Maui on the 40mm G One RS Super Race’s and they were fantastic. Maui can be hard on tires with the small volcanic rock boring through the tread, but didn’t have any issues including on the chopped up East Maui Loop.
The flat protection of Schwalbe’s gravel tires in the Pro casing anecdotally seems pretty good. Multiple high finishing Pro’s ran them in Unbound last year. Cam Jones ended up running a 50mm G-One RS in the front and then the 45mm RX in the rear. Karolina Migon Schwalbe Thunder Burt 2.10 front and 45mm G One RS in the back. She had been pre-riding on a RX in the front but switched to the TB for race day. Again anecdotal, but it seems I heard of more folks flatting on Dubs than on Schwalbes.
