The C2C Via Nirone with Campag Xenon in my LBS is IRO £740 Dobber...it was £760 a few months ago.
Look at
Evans (for want of somewhere else)...i see three models
Via Nirone, Xenon @ £674 ( i assume thats a 10 speed). Same as mine, durable on every front, been a very good bike.
Via Nirone, Sora @ £595. ( i assume 9 speed) Nothing wrong with Sora (based on my 8 speed experience)
Via nirone, Shimano 2300 @£524( i assume 8 speed) 2300 a relatively new offering (i think) set below Sora.
Personally, Shimano on an Italian bike doesnt seem right (but thats just my thoughts...lights blue touch paper
...and runs).
Lovely bike...but i'm biased
