I have an opportunity to purchase a 2002 Voyager XII with 4,700 miles on it. In researching the cycling press reviews a recurring compliant is the tendancy to "wander back and forth" and have a hard time maintaining a straight line. What has been the experience of some of you who own Voyagers in this regard? Is it true? Is it correctable and if so, how? Also, is an intercom standard on all models? I have been unable to find any intercom connections on this bike.
