Optimized to exceed limits

The Crankbrothers Synthesis DH Alloy 2.0 wheels are purpose-built for downhill racing and riding, offering a tuned system for ultimate performance on the most demanding trails. The compliant front wheel enhances grip and control through rocks, roots, and technical features, while the stiff rear wheel provides the stability and durability needed to handle high-speed impacts and aggressive cornering.

Reinforced rims, spokes, and a DH-specific profile ensure maximum strength and reliability, while modern DH Boost spacing availability guarantees compatibility with today’s downhill bikes. Proven on the toughest courses, this wheelset is designed to inspire confidence and deliver speed, lap after lap. With Synthesis DH Alloy 2.0 wheels, every descent becomes your playground.

Features: 

  • Tuned Front & Rear System: Optimized alloy wheels designed for Downhill 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 our 54t Ratchet Upgrade Kit
  • Rims covered by lifetime warranty

Tuned Wheel System

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

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

Reinforced Rim Geometry

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