Paired with the confidence of disc brakes and built with a drivetrain ready for quick accelerations and repeated efforts, the Boone 9 Disc offers sharp handling and a lightweight, responsive feel that rewards aggressive racing. It’s a dependable platform for riders who want a CX bike that handles the chaos of competition while staying efficient and composed from start to finish.
