e*thirteen Grappler Tire 27.5 x 2.5 - Radial Casing (Momentum Compound)

A full‑aggressive Enduro/DH/E‑MTB tread with radial‑ply construction for improved terrain conformity, braking stability, and comfort on long runs. The Grappler Radial in Momentum compound balances rolling speed, durability, and confident cornering grip.

e*thirteen Grappler – 27.5 × 2.5, Flux GR Radial Casing (Momentum)

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 Momentum version uses a dual‑compound rubber that balances speed and grip. A firmer 50a center compound improves rolling efficiency and tread life, while the 42a MoPo‑grade shoulders maintain high cornering traction. It’s a strong rear‑tire option, and pairs perfectly with a MoPo Grappler up front for maximum grip where it counts.
