reason	Wilier publishes no defensible conventional equivalence for its letter sizes. No authoritative source could be obtained: wilier.com and its technical PDFs answer 403 to us, so nothing manufacturer-published could be read. Retailers list letters only. Refused for absence of evidence rather than because of contrary evidence — if the source becomes reachable this is worth revisiting.
