Bought an old 1990 Trek Multi-Track 790 a couple of months ago for day-trekking. It hadn't been used, as it was sold to a 5'6" woman, and it fits me (at 5'10") perfectly, and only after replacing the bars with a shorter reach version. Man, she must have been stretched out ... no wonder it didn't get ridden. So basically it was "like-new." Oh yeah, and it has all Deore LX components, with forks drilled for low-rider racks. Stumbled across the racks for $8 in the clearance bin at Perf a couple of weeks later.
It appeared to have the potential to be set up for touring, so I got a little jazzed about the concept and started visiting this forum and getting ideas. When I got it, it had standard road bars with unpadded tape, very narrow saddle, and skinny tires. I wanted to soften up the ride and make it more comfortable. I put on a better rack, saddle, new bars, padded tape, replaced all the cables, raised the stem to the max, fit 700x28 tires (the widest I dared on these 13mm rims), and gave it a good bath.
The ideas I got here that really worked out are the Schwalbe Marathon tires (running about 20 psi lower pressure than the Conti-3000's that were on it) and the On One Midge bars. I used a photo someone posted as an example of how to setup the bars. They are a kick! Short reach and short drop, with dramatically flared drops - amazingly comfortable both from the hoods and the drops, and the brakes are equally accessible from either position. The big surprise is how easy it is to sprint from the drops. They feel quite odd, but in a good way. The tires, padded tape and improved rider position (higher stem, shorter reach) softened up the front end, and the tires and saddle softened the rear - a big overall improvement.
All-in-all, it is a versatile bike, not a dedicated long-distance heavily-loaded touring machine (with only 17" chainstays, not quite low enough gearing, and skinny rims), but I think it will do for some light touring, which is all I will probably subject it to. But it's become my most used (out of 6) bike, suitable for quick jaunts around the bay, as well as trips to the store with my grocery panniers.
