Thanks for the input guys!
I just double checked my Rockhopper, it's a 7 speed! The shifter I have on the bike now is a Deore DX. It's not the original shifter that came with the bike. I replaced the shifter with these so it would have indexing and is thumb operated. There is a guy with a webpage that shows how he fixed his shifter. Its the same shifter I have and it was due to the grease inside caking up and not allowing the parts inside to move. So he sprayed it with a solvent and it freed up. Then put in new grease and it works like new. I can give that a try, if that fails, I'll look at a replacement. Or try to find my original friction shifter.
I can't tell if the tires are dryrotted. From what I can see, they look pretty good. I put about 25 or 30 miles on them since I pulled the bike out of retirement. There are small cracks on the sidewall rubber. But I don't plan to keep these tires on there for much longer.
As soon as I can get the drive train working properly, I'll consider wheels and new tires. My wheels are still in great shape. But I'll see what I can find. And I've always wanted to look at those bar end bars so I can ride with my hands in a similar position as on the road bike.
I've since changed out the saddle and put my old road pedals on it. I did a quick search and saw a Mavic rim for about $100 that can still do the rim brakes. It was actually less at Nashbar.
