Perhaps, but he has to be able to find them. From his original question it didn't sound like he was sure about whether to keep his bike as is or upgrade. Reading into it I wouldn't think he's a mechanic, otherwise he wouldn't have asked. Ergo he'd probably have to take it to an LBS for this work to be done. They just don't stock older parts like that anymore.
I took a 10 year old MTB to a reputable shop last fall to see about getting it refurbished. It was going to cost plenty ... right around $180 for a cassette, chain, 2 chainrings and labor. That didn't include the rear wheel, which needed replaced because the spokes were fatigued, and repacking any bearings or replacing any cables. Definitely not worth it.
All derailer chains are 3/32 in inside width, and will absolutely work on a 20 year old sprocket.
The newer chains are narrower. You're saying that a 9 or 10 speed chain would work on something like a Shimano STX front end? I know that's an MTB sprocket/crank, but it's touted to be designed for 8/24 speeds.
What's octalink BBs have to do with anything.
If he goes with the newer mid-grade or higher Shimano stuff there's a good chance it's going to be Octalink.
Besides, he said he's looking primarily for lower gearing. That's an inexpensive triple crank,BB and FD. Maybe even cheaper with some bigger cogs and mtb RD to shift it.
True, provided the rest of the drivetrain isn't worn out and slipping.
He still hasn't said what he's got,so I'm not gonna write the book on all the possibilities.
Fair enough. I'm making assumptions about what he has and his mechanical level. But if he knew what you do about this he wouldn't be asking it on a forum. I still think he should stick with what he already has (tune-up included) and start saving for a newer rig with some updated technology. Older bikes can become a money pit.
