e*thirteen Grappler – 29 × 2.5, Flux GR Radial Casing (MoPo)

The Grappler Radial takes the proven, full‑aggressive Grappler tread and pairs it with e*thirteen’s advanced Flux GR Radial casing. Tall, supportive side lugs deliver predictable cornering at every lean angle, while aggressive center knobs provide strong braking and acceleration grip. The open tread layout sheds mud and debris quickly, maintaining traction in loose, wet, or blown‑out terrain.

What sets this version apart is the radial‑ply construction. By allowing the tread and sidewall to flex more independently, the tire conforms better to roots, rocks, and chatter. The result is more consistent traction, improved bump absorption, and reduced arm fatigue on long, rough descents. A 72 TPI dual‑ply casing with Dual Apex inserts provides lateral stability and impact protection without compromising the planted, compliant feel.

This MoPo version uses a pure 42a single compound designed for maximum grip. Its ultra‑soft durometer and slow rebound deliver the highest possible traction in corners, under braking, and through loose terrain. It’s the go‑to choice for front tires and gravity setups where grip matters more than anything.

Pair it with a Momentum Grappler in the rear for a fast‑rolling, high‑grip combo, or run MoPo front and rear for maximum traction on steep, technical terrain.
