Grappler RS Rear Radial MTB Tire

Grappler RS Rear Radial MTB Tire

The Grappler RS Radial uses the same rear-specific RS tread with taller center knobs and steeper ramp angles for strong braking bite, fast rolling, and rear-wheel hookup under acceleration. Shoulder knobs are proportionally taller than the standard Grappler for a smooth, predictable lean transition. It's a purpose-built rear tread for Enduro, DH, and E-MTB riding.

The Flux GR Radial casing adds radial ply construction, which lets the tread and sidewall flex independently. The result is a rear tire that tracks straighter under braking, conforms better to rough terrain, and reduces fatigue over long stages. The 72 TPI dual-ply construction with Dual Apex inserts on each sidewall keeps the tire stable under hard cornering loads without fighting the radial compliance.

Available in two purpose-built compounds:

MoPo is a pure 42a single compound designed for maximum grip. The soft durometer and slow rebound give you the highest possible rear-wheel traction under braking and through corners. When every bit of grip counts, MoPo delivers.

Momentum is a dual compound that balances grip with rolling efficiency and tread life. The center lugs use a firmer 50a durometer for faster rolling and better durability, while the shoulder lugs use the same 42a MoPo rubber so cornering confidence stays high. A strong choice for rear tires where you want speed on the pedal and grip in the turns.

Pair with a Grappler Radial up front for the most connected, comfortable setup on long, rough stages.
