it certainly appears to be a Brava.
ChroMo Lite, just refers to the type of tubing, made for Bianchi, used to build the frame
Campione del Mondo celebrates Bianchi Bicycles being ridden to several world championship victories in several classes. (not to mention several RAAM victories some very close to the mens finish time)
I have never seen this before but I love it!! Sky Yeager is a long time employee at Bianchi USA (a wholly owned subsidary of Bianchi VESPA or is it SPA?) but I always thought she did more marketing type stuff
the Brava name came and went over the years since about '84 and was normallky associated with a 105 level bike. I believe currently and starting in the mid 2000s it became a performance (highend) hybrid. what components are on this? is it lugged or tigged?
PS OH this is an '05 with a tigged frame, Sora shifters/derailleurs and a sugino crankset
value would depend on who was interested in it. it is a bigger bike wich hurts value but it looks to be in good shape.
