The Grappler RS is a rear-specific tire built around what a rear wheel actually needs: strong braking bite, fast rolling speed, and cornering support without excess drag.
Taller center knobs with steeper ramp angles — compared to the standard Grappler — deliver more braking control and rear-wheel hookup under hard pedaling. Shoulder knobs are proportionally taller for smooth, predictable lean transitions.
The Flux GR casing features 72 TPI dual-ply construction with GR Apex sidewall inserts, giving the RS the durability to handle the abuse rear tires take in Enduro, DH, and E-MTB riding.
Available exclusively in MoPo compound — a pure 42a single-compound formulation built for maximum grip. Its soft durometer and slow rebound deliver the highest possible rear-wheel traction under braking and through corners.
Pair it with a Grappler Flux GR up front for a grippy, well-balanced setup with strong hookup and braking performance at both wheels.

- Enhanced braking control and rear-wheel acceleration grip
- Flux GR 72 TPI dual-ply casing with GR Apex sidewall inserts
