Think they are 26mm wide at the brake track, can't remember the spec. I only had issues with 28C overall diameter rubbing the inside rear brake caliper in the winter months aka rain debris. Summer months wasn't an issue with 28s, no rocks were sticking to the tires. Any how I'm on on 26c gravelking file threads, over all diameter is much smaller than 28c conti GP4, clearing the brake caliper. I did have to adjust the cable slack for the width of these rims.
Cross winds, the first hit of the wind moves thew bike a bit, but its stabilizes pretty well afterwards. I'm not sure a lighter rider would fair so well if they ride in wind all the time. I'll see if the assement changes as I put more saddle time in. The overall ride vs alum is night and day smoother. The hubs are DT swiss 240 loud, so no ninja wheel sucking anymore. 10* engagement is also harder to hide the soft pedaling in a group.
