57mm of clearance means the new Addict Gravel swallows 2.2-inch MTB rubber, standard. That's not a tolerance for oversized tires — Scott built the geometry, slack head angle, and low bottom bracket around 50mm as the baseline width. The 60 percent compliance gain in the rear triangle comes from a slimmer seat tube and lowered seat stays, not just wider rubber cushioning the ride. This is a bike engineered for the wide-tire era, not a road-derived frame stretched to fit one.
