discarded figure	the listing prints 42 cm beside its letter size
reason	The centimetres retailers print for Colnago are millimetre seat-tube lengths ('420 mm = XXS' … '570 mm = XXL'). The resulting ladder sits 4-5 cm below the conventional scale at every rung, which is the signature of a measurement rather than a name. Nobody names a road frame '530 mm'.
