Coop, a bike that old of that level is worthy of some "tuning upgrades", so you might consider a quick makeover. Beyond that, upgrades aren't your best move on a "platform" that's limited by its nature. I'd suggest:
--new brake pads: Kool Stop dual compound, low profile
--new grips: update with something to give the bike a new feel.
--new tires: update with higher volume, and check out the WTB MutanoRaptor 2.4 for the front tire...killer for rigid bikes! Try a Velociraptor 2.1 or similar for the rear (narrow and aggro knobs).
--lube/clean or replace cables for derailleurs and brakes
--lube/clean or replace chain ** but don't replace it if the cogs are worn, just lube in this case**
--saddle: how old is that thing? Seats have come a long way since what came OEM on the 820.
--dial in those derailleurs, tune the wheels for true
With that, the old 820 should be better than it ever was and a load of fun to ride. Something to get your appetite whetted for a later upgrade and then a loaner bike you'll be proud to use to lure new victims with.
If you really want to upgrade more, there's one thing I do on rebuilds of old bikes for buddies: Avid 7 levers and brakes. They're the most bang-for-the-buck system you can get in vee-brakes, are super easy to tune, are lighter than what you'll trade them for and work great. You can find them online in combo-pack deals for levers and brakes together. Still get the Kool Stop combo pads if you do this, btw.
you can upgrade parts as they fail. if your riding interest grows then it's easy to justify upgrading to another bike that has all the goodies. :thumbsup:
