Control & stability for E-MTB riding

The Crankbrothers Synthesis E-MTB Alloy 2.0 wheels are designed to meet the demands of pedal-assist mountain biking, offering the perfect balance of control, durability, and stability. This wheel system features a compliant front wheel for enhanced grip and precision through rocks and roots, paired with a stiff rear wheel to withstand impacts and deliver stability during cornering loads.

With upgraded materials, refined finishes, and advanced rim profiles, the Synthesis E-MTB Alloy 2.0 takes our front- and rear-specific tuned wheel design to the next level. Whether youre conquering steep climbs or powering through challenging descents, these wheels provide unparalleled directional control, predictable handling, and muted trail chatter for an elevated riding experience. Backed by a lifetime warranty, the Synthesis E-MTB Alloy 2.0 wheels are ready to take your E-MTB adventures to the next level.

Features:

• Tuned Front & Rear System: Optimized alloy wheels designed for E-MTB riding, with front- and rear-specific tuning to meet the unique performance demands and loads of mountain biking
• Compliant tuned front wheel improves handling, grip and cornering control with an inner rim width that supports a wider tire profile, increasing volume and contact patch for improved turning performance
• Stiff tuned rear wheel improves stability and tracking at speed by absorbing peak loads. A narrower inner rim width optimizes rolling resistance and sharpens tire edges for improved grip
• A reinforced rim construction with 6069 aluminum and a shot-peened finish provide superior impact resistance and fatigue strength
• Available equipped with Industry Nine 1/1 with 4 degrees of engagement, or Crankbrothers Ratchet hubs with 10 degrees of engagement, upgradeable to 6.6 degrees of engagement with our54t Ratchet Upgrade Kit

TUNED WHEEL SYSTEM

Wheel stiffness maximizes power transfer and speed, delivering snap response and better tracking for confident cornering. Compliance enhances control and grip, reducing trail chatter and maintaining ground contact for faster, smoother turns. The solution is a perfect balance between a compliant front wheel for precise turns and a stiff rear wheel for ultimate power and tracking, creating the ultimate ride quality.

IMPROVED MATERIALS & ELEVATED FINISH

Built from premium 6069 alloy, our rims deliver significantly higher tensile, yield, fatigue, and shear strength offering better resistance to dents, cracks, and deformation for unmatched durability and long-term performance. As for the shot peening, it strengthens the rim by hammering the surface in a controlled way, creating a hardened outer layer that helps prevent cracks and failures. As a result, Synthesis Alloy 2.0 has an improved bending strength, greater crack resistance, and a longer lifespan for better performance ride after ride.

REINFORCED RIM GEOMETRY

An updated rim geometry includes thicker rim walls in key areas most susceptible to impact damage, resulting in class-leading durability.
