Hi all, I just bought my first bike, a used bianchi volpe. It seems to be in great shape, it has all shimano RSX components from the STI levers down to the hubs and skewers. I did a lot of research before buying and never ran across anything about RSX. Any opinions or warnings about this? I'm definitely keeping it for a while, but i'd be interested in what/how to upgrade. I already noticed that it was a bit tough shifting going uphill, but that may be settled w/ a tune-up. General used bike advice also welcome! Thanks!
