An idler pulley is integrated to manage chain growth and pedal feedback, ensuring efficient pedaling despite the high pivot.
Aluminum Frame with Ride Aligned™ – The lightweight and durable aluminum frame is designed with Norco's Ride Aligned™ system. This approach ensures optimal geometry and suspension kinematics for each frame size, providing a balanced and predictable ride feel for all riders.
