[Retro junkie]

HI ALL , I HAVE A PAIR OF THESE LACED TO BLACK DEORE LX PARALLAX HUBS WITH NEW CHARGE SPLASHBACKS RUBBER. JUST WANTED TO KNOW HOW PEOPLE RATE THEM AND DO THEY WARRANT A PLACE TO LIVE ON MY 1992 ROURKE MTB

Sounds like a solid wheel to me, not light though!
Are they a bit 'late' for full period build?
If neither of these is a problem then....

d521s are downhill rims, bombproof but heavy
