Length measurements are in millimeters; HTA and STA are in degrees. ETT means effective top tube. Values prioritize RideDNA calculations. * RideDNA calculated (including corrections where published values differ). Unmarked values are manufacturer-published; matching independently calculated values are identified in their source notes. † Manufacturer did not publish this dimension; † alone means no reliable value is available. ‡ Staff reference or source not confirmed; see the source note. Open Geometry Audit for the original published values, calculated geometry, and deltas.
