What to check when buying used

Inspection

Frame condition

Inspect the frame, fork, welds, and high-stress areas for cracks, dents, or prior repairs.

Inspection

Drivetrain wear

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

Inspection

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.

Inspection

Suspension service

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

Inspection

Frame pivots & bearings

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