Maintenance Tips
- Clean the frame after trail, mud, or wet rides to prevent corrosion and preserve the steel finish.
- Inspect chromoly frame and fork regularly for paint chips, rust spots, dents, or stress damage; touch up exposed steel quickly.
- Apply internal frame rust inhibitor annually, especially in wet, snowy, or coastal environments.
- Grease all threaded interfaces (bottom bracket, headset, thru-axles, bottle/rack mounts) to prevent seizing over time.
- Check suspension-corrected fork, headset, and dropouts frequently for tightness and alignment after aggressive trail riding.
- Ensure disc brake mounts and rotor bolts stay clean, tight, and properly torqued for consistent stopping power.
- Maintain drivetrain (chain, cassette, chainring) with frequent cleaning and lubrication, especially after muddy rides.
- Clear tire and frame space of packed mud or debris, especially with high-volume 29+ tires.
- Avoid high-pressure washing to protect bearings and frame seals from water intrusion.
- Store indoors in a dry place to extend frame life and protect finish durability.
