Notes from MyBikeThing: The Quadra 21R is one of the iconic mid-90s MTB forks — the bright yellow colorway and RockShox graphics are pure nostalgia fuel. This one is in genuinely usable condition, not a shelf queen or parts donor. Perfect for a period-correct build or getting that old hardtail back on the trail.
