KEY FEATURES

• Tuned Front & Rear System: Optimized alloy wheels designed for E-MTB riding, with frontand 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 or Crankbrothers Ratchet hubs
• Rims covered by lifetime warranty.
