I've posted here before on my '89 Schwinn Voyageur that I intend to try and ride to New York from San Antonio Texas beginning in early June.
Towards that end I've been putting in long miles on the bike loaded with 50lbs+ of stuff.
This week the bike is in pieces as part of a 16 hour tear-down/rebuild bike maintenance class. The bike is sound everywhere except for the most questionable component; the rear wheel hub. It has loosened up more than I would like since having it regreased/adjusted not too long back, and also tho' without obvious wear it seems to defy perfect adjustment even at the hands of the instructor. Apparently Schwinn was cost-cutting in '89 and installed only average quality hubs.
Then too, tho having 36/40 spokes front and rear and still in good shape the rims are only single wall, an anachronism in this day and age.
Fortunately I still have more than three months to put lots more loaded miles on the bike before the tour to see how that rear hub in particular holds up.
Worse comes to worse, turns out 700C wheels are a drop-in proposition on this bike (it presently has 27" wheels), which would also allow me to upgrade from the seven speed old-style freewheel. The downtube shifters are friction and so compatible with any number of "speeds".
If it turns out I DO need to replace that back wheel.......
I have no interest in flash or uber-lightweight wheels, just a solid set that would get me from here to there. I'm hoping ballpark $300 or less would do it. If not I'd consider just switching out the back for a 700 and running the original 27" up front, or else bite the bullet and spend more.
