• Dual brake compatibility – Rear hub is configured for V-brake use out of the box and accepts optional Center Lock disc brake rotors for riders transitioning to disc systems
• Double-wall XLS rims – 6061-T6 aluminum construction with optimized profiles for front and rear applications balances strength and weight for race conditions
