• Inspect the fork stanchions for scratches or coating wear, look for oil or dirt rings at the seals, and cycle the fork through its travel while checking for binding or bushing play.
• Ask for dated fork-service records. A clean exterior does not establish the condition of internal seals, oil or bushings.

• Shift through every available gear under light load. Hesitation, skipping or inconsistent indexing can reflect wear, damage, poor adjustment or mismatched replacement parts.
• Measure chain wear with a compatible gauge and inspect chainring, cassette or freewheel teeth. A new chain does not rule out wear in the remaining drivetrain.
• Turn the cranks slowly, feel for rough bearings and check for side-to-side play. Inspect crank arms, chainring bolts and pedal threads for looseness or damage.

• Inspect pads and braking surfaces, check the complete cable or hose path, and confirm both controls feel consistent and return cleanly.

• Apply the front brake and rock the bike to check for headset play or notchiness. Inspect the stem, handlebar and clamp zones, then confirm every fastener and control is secure.
• Check that the seatpost moves for adjustment and that the saddle, post and clamp hold securely without cracks, severe corrosion or damaged hardware.
