purchased a bianchi volpe on e-bay. the seller wasn't sure of the year. i would like info on how to research this bike. forest green-shimano rsx rear der, front der, crank set rsx 46-36-26 this bike has new ultegra bar end shifters. i think the rsx components would give the year away but not sure. any thoughts or info would be greatly appreciated. thanks - make a great day!
