I was wondering what characteristics make a bike an italian, an english, a japanese, an american or a french bike. Other than who made it where. It seems like reynolds and wrap-around stays for the english bikes. ****ty paint and ISO threading for italian bikes. Proprietory sizing and nervex lugs for frenchies. What makes a Keirin bike very japanese? What makes you say "looks italian," or "looks french" when we come across a bike on the street missing its decals. Why do people call California Masi's very Italian? Fork Crowns: Sloping? Flat? Twin Plate? Triple Plate? Internally Integrated Fastback Seatstay Binders? Long Point Lugs, stamped dropouts, where do these all fall on the globe of bicycle styles by nation.
