I know that I am attempting to resurrect the dead......but!

I have a 1996 GT Rebound that is need of repair. The crankset is badly worn, and has broken teeth(courtesy of last ride through Cherokee NC mountains). All of the drivetrain components are original, so they all need to be replaced. Looking for advice on upgrade vs direct replacement parts (if I can find them).

Current set up is:

Crankset - ShimanoAceraX, 24/34/42 teeth.
Bottom Bracket - Shimano BB-CT91, 122.5 mm spindle
FrontDerailleur - Shimano AceraX top-swing,bottom-pull/clamp-on 28.6 mm.
Rear Derailleur - Shimano Alivio.
RearCogs - 7-speed, 11 -28 teeth.
Rear Hub - Shimano AceraX FH-290
Shift Levers - ShimanoAlivio MC15-C RapidFire Plus.
Brakes - Shimano Altus brakes,Shimano Alivio levers

I am a complete novice dealing with this subject. Any advice or suggestions would be greatly appreciated.
Thanks!

Can you bring the bike by to the shop I work at? It will be VASTLY easier for anyone to actually touch/see the bike before any real solid advice is had. Andy

If you truly have to replace all of those components, or even most of them, it would probably be better to consider a new bike or at least a newer, better condition used bike. The bike you describe was a lower line when new and almost everything on it is obsolete.

Replacing all of the components is a recipe for turning a cheap old bike into an expensive old bike that has a few new parts.

My bet is that a good cleaning followed by new brake pads, cables and housings, and maybe tires, is all that bike probably needs. Of course, like Andrew Stewart said, I haven't seen the bike.

On those broken crankset teeth - take a close look at the teeth exactly opposite from the broken ones. If you see a set of similar teeth, that's a design feature for improving shifting.

Welcome to the forum.

Be sure that the chain rings are actually worn or broken. The mid '90s was when sculpted teeth began to appear and have been confused as broken by many people.

Generally a complete overhaul is the only requirement to returning a bike to service. This includes consumables nearing the end of their life. As mentioned earlier, it's nearly impossible to offer specific suggestions without laying hands on the bike or at the least photos.

Andy, thanks for the response. Unfortunately, I am a bit south of you, but if I was in your area, I would stop in. Been some years since I have been in Rochester, you have got me thinking about Nicks, and a nice Garbage Plate!

We have nicer food places these days Andy

I appreciate the response from each of you.


I do not want to put a large amount of cash into the bike, especially if it would start getting to the point where a newer used or even new bike would be more cost effective.


After reading the posts, the teeth are sculpted, and though they do have some wear, I believe there is still some life left in the old clunker. Found Park Tools website, looks like it ought to be able to guide me through needed service.


Was going to throw some photos up, but photobucket keeps throwing error messages at me.


Thanks again!
