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 →- FrameLook closely for dents and hairline cracks around welds, the head tube and bottom-bracket area. Cosmetic scratches matter less than a change in shape or a crack line.Inspect the frame and fork →
- SuspensionAsk when the rear shock was last serviced. Check the shaft and seals for damage or oil, cycle the shock through its travel and test every suspension pivot for play.Evaluate the suspension →
- 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.
