ethirteen Grappler Race Alloy e*spec Enduro Wheels Info

The e*thirteen Grappler Race Alloy e*spec Enduro Wheels are purpose-built for the unique demands of full-power e-MTB riding, delivering a lively ride feel backed by exceptional strength and long-term durability. Developed and refined through multiple World Cup racing seasons, these wheels are engineered to handle higher system weights, increased torque, and sustained abuse on aggressive terrain.

At the center of the system are welded 6069 aluminum rims with a 30mm internal width, striking a smart balance between lateral stability and vertical compliance. The rims feature a low-profile shape that enhances frontal compliance, helping reduce rider fatigue while improving traction and control on rough trails. Compared to previous e*spec Plus generations, the Grappler Race Alloy wheels are engineered to be up to 228% stronger, making them an ideal choice for hard-charging enduro and gravity-focused e-bike riders.

The ride quality is tuned for responsiveness and precision. A low rim profile paired with double-butted spokes creates a dynamic feel that responds quickly to rider input without transmitting unnecessary harshness. The e*spec-specific rim construction is reinforced compared to analog versions, ensuring reliability under the added mass and power output of modern e-MTB systems.

Out back, the dedicated e*spec rear hub is designed to withstand high drive torque and heavy loads. An oversized hub shell, large 6808 bearings, a steel axle, and a 32-spoke configuration improve stiffness, durability, and bearing longevity. The freehub offers 6 degrees of engagement, balancing quick power delivery with reduced pedal kickback for smoother suspension performance.
