e*thirteen Grappler RS Tire 27.5 x 2.4 - Flux GR Casing (Mopo Compound)

e*thirteen Grappler RS – 27.5 × 2.4, Flux GR Casing (MoPo)

The Grappler RS is engineered specifically for rear‑wheel duty, delivering the braking control, acceleration grip, and cornering support that aggressive riding demands. Compared to the standard Grappler, the RS features taller center knobs with steeper ramp angles for stronger braking bite and improved rear‑wheel hookup under power. Taller shoulder knobs keep the lean transition smooth and predictable on loose or technical terrain.

Built on the Flux GR casing, the RS uses a 72 TPI dual‑ply construction with GR Apex sidewall inserts for stability, impact protection, and the durability required for Enduro, DH, and E‑MTB abuse.

Available exclusively in MoPo — e*thirteen’s pure 42a single compound — the RS delivers maximum traction with slow rebound damping for control under hard braking and through rough, off‑camber corners. When every bit of rear‑wheel grip matters, MoPo delivers.

Pair it with a Grappler front tire in Flux GR for a balanced setup with strong braking and cornering performance at both wheels.
