Everything is original except for saddle, tires and forks. I have a sentimental attachment to this bike but would like to bring it into the 21st century. I'm looking to make this a nice project bike but don't know much about the compatibility of new components on this model. Things I would like to upgrade are; Suspension forks, wheel set and tires, disc brakes, front and rear chainrings, shifter/derailer, crank arms, handlebar and any other related parts needed. Looking to create a real retro beast. The bike had the stock rigid forks that I upgraded myself to RockShox JudyXC back in the day but those elastomer pistons are toast. Since it's been a while that I traded serious riding for changing diapers I figure It's time to take the bike out of retirement and make it something worth riding and passing on to my son when he goes off to college in a couple of years. Any advice and/or guidance would be much appreciated. Thanks
I had a similar era KHS Alite3000 - Most moving parts had been replaced from wear over its life, but pretty much original. AT 10.5kg, RockShox Judy's, XT components etc, it is a light, fast and agile bike. Like you, I gave up serious riding for kids, got back into it last year. The KHS, despite my fondness for the bike, has been given away in favor of a new bike. Like cars, bikes have moved a long way in 20 years, and the "practical" option is to replace it - especially if you ride off road.
The main reasons for me to replace rather than upgrade were cost exceeding the total cost of a new bike, no disk mounts and the old frame geometry not suitable for modern forks- back then 50mm was considered long travel, now 120 typical for XC.
If you really want to upgrade it, cheapest bet would probably be a "donor" bike. Getting decent forks with V brake bosses is next to impossible, so disks on the front would be easiest. Unless you got some second hand quality forks with V brake bosses.
What I would do is tune it up, replace any obviously worn out bits, and buy my son a new or 2-3 year old secondhand bike.
I have a similar 1995 Cannondale M-900 in Vipper Red color version. Some original parts have breen replaced but for original ones, trying to maintain muy bike in its optimal and original condition. I am proud of that and like very much to ride on my old but pretty M-900. To bring a very old bike onto a mew era is not only very expensive but thecnically almost impossibe. I recomend to buy a new one for your kid. Orlando
It seems like you're willing to buy all new componentry, so you have a lot of flexibility.
It doesn't look like there are many compatibility issues with it except the issue with disc brakes (rear wheel spacing is 135, front fork should be 1 1/8", Just get a new bottom bracket with your cranks). I'd personally just put a disc in the front and then a good set of V-Brakes in the rear so you don't have to do some hack to retrofit discs in the rear.
After that, just grab a short travel front fork, a new wheelset, a 10 speed groupset with rapidfire shifters and should be pretty much up to modern spec for most parts.

I love keeping vintage gear on the road. You'll probably wind up putting more money in to this than a decent entry level bike though.
