What to check when buying used

Drivetrain wear
Check chain stretch, cassette teeth, chainrings, and shifting under load before negotiating price.

Wheel condition
Inspect rims, hubs, spokes, and bearing play; ask about the tire age and any prior wheel rebuilds.
Inspection
Service history
Ask for service records covering bearings, brakes, drivetrain, and any frame or fork warranty work.

Suspension service
Confirm fork lowers and rear shock service intervals; ask for the most recent service receipts.

Cycle the suspension off the bike to feel for play, grit, or noise in pivot bearings.
