reason	Cannondale publishes no defensible conventional equivalence for its letter sizes. Cannondale's Topstone dual label is a seat tube: XS=41 S=46 M=51 L=55 XL=60, a 5 cm step per letter against the conventional scale's 2-2.5 cm, and XS sits 8.5 cm below where the market puts an XS. The harvester rejects the pooled ladder for the same reason (implausible-step); this records the verdict so the stated centimetres are actively discarded rather than merely left unmapped.
