I too have a Randonee. Mine is about 15 years old. Only one long tour under it so far, that was Portland to San Francisco on the ACA Pacific coast route. Other than being a little short on gearing for a couple of the more severe climbs, it did great. In the 15 years since, it has done commute duty, being left out in the hot Arizona sun all day, and other than the paint being faded, it works just fine. Oh yes, the STI shifters that my year came with gave up the ghost a year or so ago, and will replaced with downtube levers . But the New models use bar end shifters anyway, which is a better choice.
From what I see in the specs, the new ones are even better yet in terms of the equipment that they have on them. So you should be fine.
I intend to use my now 15-year-old bike to do the Trans Am next summer. Other than the smallest chain ring which I have already swapped from a 26 to a 24, the previously mentioned shifters, and replacement of wear items, I expect to use it as it sits, and doubt I'll have any issues.
When I bought mine, the Randonee was more like half the price of alternatives such as TREK. Nowadays it's still cheaper though not by nearly as much. Still when you consider that it is cheaper and you get 10% back at the end of the year, I think it's one of the better values out there.
Just the two cents from a satisfied owner.
