Marzocchi Plunger Shaft and Topcap Kit
Best essential upgrade for mountain bikers performing their own suspension maintenance.
Swap your air spring for a coil setup to unlock that buttery, linear feel that air simply can't replicate on technical terrain. You’ll trade the infinite adjustability and weight savings of air for consistent, ground-hugging traction, making this the ultimate upgrade for riders who prioritize grip and suppleness over everything else.
