e*thirteen Grappler Tire 29 x 2.5 - Flux GR Casing (Mopo Compound)

A full‑aggressive Enduro/DH/E‑MTB tire built for maximum grip and control. The Grappler in Flux GR casing uses a 72 TPI dual‑ply construction with GR Apex inserts for uncompromising durability and cornering support, paired with the ultra‑soft MoPo 42a compound for the highest possible traction.

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

The Grappler is a full‑aggressive tread designed for riders who demand maximum control on loose, wet, rocky, and blown‑out terrain. Built for front or rear use across Enduro, DH, E‑MTB, and aggressive trail riding, it features tall, supportive side lugs for predictable cornering at every lean angle and aggressive center knobs for powerful braking and acceleration. The open tread layout sheds mud and debris quickly to maintain traction in challenging conditions.

This version uses the Flux GR casing — the full‑strength option for gravity and E‑MTB use. A 72 TPI dual‑ply construction with GR Apex sidewall inserts provides exceptional puncture resistance, stability under hard cornering, and the impact protection needed for high‑speed, high‑load riding.

The MoPo compound is e*thirteen’s 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.

For a balanced setup, pair MoPo up front with a Momentum Grappler in the rear — or run MoPo front and rear for maximum traction on steep, technical terrain.
