All

I have a 1993 LX groupset (7-Speed) on an a rigit MTB frame of the same era. It has served me well but various parts of drive train are starting to wear out. Any views on if I should just start to swap out the parts for newer upgrades or stick with it as it was a strong and quality set? I could probably over a few months pick up decent (used) replacement parts so stick with more or less the same build albeit it wont be cheaper than probably buying newer parts.

Thanks
