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

The Grappler is a full‑aggressive tread designed for riders who want maximum control on loose, wet, 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 Momentum dual compound balances grip with rolling efficiency and tread life. A firmer 50a center compound improves rolling speed and durability, while the 42a MoPo‑grade shoulder rubber keeps cornering confidence high. It’s an ideal rear‑tire choice or a fast‑rolling front option for riders who want speed without sacrificing grip.

For maximum traction, pair a MoPo Grappler up front with a Momentum Grappler in the rear — a proven setup for aggressive riding.
