Used-frameset inspection
If you’re buying this frameset used
Before buying: confirm the serial number and exact model, inspect frame and fork alignment, and inventory every included axle, hanger, clamp, headset part, cable guide and proprietary fitting.
Inspect the frame and fork →- FrameInspect the frame in bright light, especially around the head tube, bottom bracket, chainstays and clamped areas. Look for cracks, ripples, crushed sections or signs of a previous impact.Inspect the frame and fork →
- Included hardwareInventory every axle, hanger, clamp, headset part, cable guide, frame plug and proprietary fitting included with the frameset. Confirm replacement availability before treating a missing small part as insignificant.
- AlignmentSight along the frame and fork from several directions. Confirm that the fork, rear dropouts, head tube and other visible interfaces appear straight; professional measurement is appropriate when alignment cannot be established visually.
