Notes from MyBikeThing
Pulled from our Olmo teardown — bulletproof Italian craftsmanship riding on French Simplex hubs, a pairing that speaks to how international a serious period build could get. Simplex is best known for derailleurs, so a hub-shell stamped with their name is a less common find for collectors and restorers chasing period-correct, fully-branded builds.

You put in the miles, we put in the work! 30-day Guarantee, rest assured of fit, function and condition.
