Thank you for your interest in this excellent Cannondale lefty with a history of moderate use. There are surface marks and scratches. The suspension action is compliant and consistent. The electronic lockout button does activate an LED light when pressed. The lockout does not engage. There is no record of service. It includes a 95 mm x 31.8 mm stem/steerer. The steerer is missing the threaded base plate that helps secure it to the clamps.
