Maintenance Tips  

• Clean frame, linkage, and drivetrain after muddy or wet rides to prevent grit damage and premature wear.
• Inspect carbon frame and swingarm regularly for cracks, chips, or impact damage—especially after crashes or rock strikes.
• Service suspension pivots and bearings on schedule; check for play, creaks, or stiffness before every ride.
• Keep SRAM Eagle 90 Transmission drivetrain clean for precise shifting and long-term reliability under load.
• Check derailleur mounting, crank interface, and all bolts regularly due to high-torque trail riding.
• Inspect fork and rear shock for air pressure stability, seal wear, and oil leaks; follow manufacturer service intervals.
• Maintain brake system (pads, rotors, calipers) with frequent inspection due to aggressive trail braking demands.
• Grease pivot hardware only where specified and use correct torque values to protect carbon interfaces.
• Avoid high-pressure washing near pivots, bearings, and drivetrain components.
• Store indoors in a dry, stable environment and re-check torque settings after initial rides as parts bed in.
