Just an old mans opinion and from a totally non-nationalistic view. Purely based on riding experiences on numerous machines. When I could spin the pedals in the 1960's! Road: Italian Cinelli Super Corsa. France Arligiue. Britain Armstrong 531DB Nervex Pro. Belgium Dossche-Sport. Track: Italian Fiorelli. France Sauvage. Britain Russ. Belgium Rik Van Plume. America Schwinn. Never road an american road bike unless you can count a Dave Moulton. Most countries have turned out some pony (pony &trap=crap) machines including I am afraid to say Britain. Have ridden some real horrors from some of our supposedly finest makers.
Best wishes and be lucky. Michael Butler Huntingdon UK.
