• Clean frame, fork, and drivetrain after trail or muddy rides to prevent dirt buildup and corrosion.

• Inspect steel frame and welds regularly for chips, scratches, or early rust spots.

• Touch up exposed metal promptly to prevent long-term corrosion.

• Apply internal frame rust inhibitor periodically, especially in wet or winter conditions.

• Check drivetrain for wear, proper shifting, and maintain regular chain lubrication.

• Inspect headset, bottom bracket, and wheel interfaces for smooth operation and correct torque.

• Ensure rigid fork, mounts, and bolts are secure and free from debris.

• Store indoors in a dry place to protect steel durability and finish.
