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