>>1821437>XTRXTR isn't peak classic mtb. XT is. It's a better looking groupset, sharper corners, cleaner lines, wheras XTR is chunkier and has more rounded aero-profile parts. XT speced peak thumby which work better and make more sense for a bike that now doesn't suit technical riding. Even back then the thumbies were more desirable than STI.
XTR also more heavily overlaps with suspension and v-brakes. It's mostly 'bad modern' rather than good classic
If i got XTR parts i'd want em on a touring bike for bling but that era of 'vintage mtb' is not the peak. You know this yourself trying to essentially backpedal through time to put a rigid fork on your bike.
