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

Inspect rims, hubs, spokes, and bearing play; ask about the tire age and any prior wheel rebuilds.

Service history
Ask for service records covering bearings, brakes, drivetrain, and any frame or fork warranty work.

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