I think it can be done. An extra inch of travel (or length, 25.4mm= 1") in a front fork only changes the head tube angle by approximately 1 degree. If you put an 80mm travel fork on it, you would most likely be OK, it would not change your head angle by all that much. The one problem you may have, is your current steerer 1" or 1-1/8"-you probably won't find a 1" headset and fork. You'd have to replace the headset with a 1-1/8" threadless headset, buy a new stem (with spacers), and get a fork-watch for old models or OEM "take offs"-I got a Manitou Axel for $79 from Jenson, to put on an older bike. They were OEM and the steerer had been cut, but was OK for the bike I was putting it on. You'd probably want V-brakes (if you don't already have some). For the bike I was fixing up, I had the brakes, so all I needed was a fork, stem, and spacers. Did the installation myself-and without a fancy headset press. If you really like the bike, and it can use a 1-1/8" headset, I'd go for it-watch the web stores for closeouts-you can find bargains.
