    SONAR JR

    STREET OR TRAIL, GO-ANYWHERE PERFORMANCE
    The Opus Sonar Jr. is a smaller version of our ever-popular Sonar mountain bike. We gave it a shorter crank and stem to fit smaller riders. What we didn't change? The Sonar's great handling and affordable performance. It's a ride with plenty of street and trail cred. Hey, what else could you ask for?

    • Lightweight frame
    • Suntour XCT 100 mm fork with plenty of plush travel
    • 21-speed Shimano drivetrain
