The Schwalbe Magic Mary Pro Tubeless Radial Tire runs a Gravity Pro casing, Schwalbe's toughest construction, built to hold its shape through hard braking and cornering loads without folding under pressure. Strong shoulder studs and V-Groove tread let every knob dig into loose or muddy ground, while angled center knobs keep the tire rolling efficiently between the moments that actually demand grip. Underneath all of that sits a radial carcass, a construction choice that changes how the tire deforms on rough, high-speed terrain rather than just how it holds air. What Our Gearhead(R) Experts Are Saying:"I hit a braking bump section at speed that usually kicks the back end loose, and the tire tracked straight through it instead of stepping out. That kind of high-speed composure is what a tire built specifically for gravity riding is supposed to deliver, not just survive."
