tra Gold e Silver,non c'è cosi tanta differenza ne di prezzo ne di prestazioni.
però la stump ha la silver tk , e con la gold la differenza tecnologica dovrebbe esistere eccome..... molla debon air vs solo air , idraulica turnkey vs motion control .... le caratteristiche salienti eccole qui :
Motion Control Damper
The Motion Control damper is RockShox's mid-range emulsion damper — it’s not a sealed unit, meaning air can mix with the oil as the fork actuates, leading to less controlled damping after repeated hits.
TurnKey Damper
The TurnKey damper is RockShox's most basic and affordable option found on the entry-level forks. As a basic emulsion damper, the TurnKey offers the least controlled dampening.
DebonAir spring
With a high-volume negative air spring and minimal breakaway force for small-bump compliance, the DebonAir spring is RockShox's flagship air spring.
Solo Air spring
The Solo Air gets its name because you only have to add air to the one valve, and it will equalize the negative pressure on its own. In years past, RockShox offered a Dual Air spring that required you to pressurize both the positive and negative air chambers.
ps: l'idraulica turnkey è quella basica della xc 30 e che, a detta di qualcuno qualche post indietro, non costituirebbe upgrade alcuno rispetto all'inesistenza di idraulica della forca originale della st530 che hai ....
