My secret Italian source has this neat looking Nesti time trial bike for sale for about 500€, shipped/negotiable. The size is 55x55cm. There's plenty more detailed pics and the bike geek in me really loves the rare Ofmega Mistral cranks on the bike. IMHO the coolest crankset design ever.
Anyway if you're interested, send me a message and I'l hook you up. The guy has more interesting geared Italian gems for sale too, like a real sweet 1970s Masi Corsa, a Bianchi, a Rossin, a Tommassini etc.
