Geometry
Manufacturer-published geometry normalized for consistent archival comparison. Effective top tube and reach remain separate measurements because they describe different aspects of fit.

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 →
- 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.
