Road Cycling - Should I buy a new bike?

I have a 1991 Trek 2100 with a carbon fiber frame. It has Shimano 105 (7 speed cassette) group. I stopped riding it many years ago after a friend got hit by a car (I took up mountain biking) I want to start riding on the road again. Living by the beach has rusted out the wheels, cables etc.
By the time I change the bottom brackets, wheel sets etc I will have rung up a bill between $300-500. The frame and non-rustable metals appear to be in good shape. Is it worth fixing this bike up? Or should I just break down a buy a new bike?
Thanks Scott

Well I think you should ask your self. How much road riding am I going to do? Do I have some extra cash? Do I have the space for another bike? if you say not much riding but the cash, and the space are not problem. I would upgrade the current bike...BUT If lots of road riding is to be done then I would buy the NEW bike. Hope this helps...

Yes

Consider in your math the value you might receive from the 2100 frame set only if you were to sell it. And consider if you were to rebuild it what the value to you would be.

If it were me (knowing the little detail provided and knowing my financial situation) I would probably take a route that would allow me to fix or rebuild the 2100. I am a tinkerer and would look at that as a fun project.

Is there anything wrong with the wheels other than the rust? If not, bust out some steel wool and/or CLR and go to town. If the rims and spokes are toast but the hubs are good you can have new wheels built around the same hubs. Handbuilt wheels done by someone who knows their stuff are a beautiful thing. I had new wheels built on my old hubs and a new bottom bracket and cables done on my road bike about a year ago (before I started doing more of my own work), and it ran me about $300.
My bike is also 90's with downtube shifters, and to me it was money well spent because I love the bike and this will keep it running for many more years, but if I had to do it over I would have done more of the work myself, or at least tried.

None of this means much if you don't love the bike, and if that's the case maybe it's time to get something new. You will not be able to get a better new bike for $300 than this one though, and if a new bike is going to be subjected to the same weather conditions and storage, you may not be that better off in the long run.

It this were my bike I would get the lightest steel wool I could find and maybe some CLR and go to work on the rust, run some new cables (run the cable and THEN cut it) and try to get the shifting and brakes in the ballpark and then take it to the shop for further tweaking and installation of a new bottom bracket if needed.

There is never a good reason to miss an oppertunity to buy a new bike. (ok that isn't true...but as long as you have the money and your family isn't going to starve, go unclothed or whatever, I say go for it :D )

Wrong place to ask that ? YES!!!!!!! :D

Pwned!!!...

Haha, someone who signed-up in August of 2000 is still a "Newbie" because it was probably his first and only post.

Damn that post was made over half a decade ago!

Ghosts in the system.....wonder if the guy ever got his new bike, stayed in cycling? Why would he have left a decent bike in position to corrode?

How timely!

Um, I mean for me.

I have a '98 Trek 2120. Same as 2100 but with a triple. It rides fine, fits me, and everything is in good shape.

Except the wheels. They suck. I've had to stop in the middle of long rides and true them up more than once.

I am trying to decide whether it's worth putting any money into this old bike by upgrading the wheels, or just buy a new bike.

Amazing, the answer is still a resounding YES!
