Sprindex Adjustable Coil Spring

Adjustable base spring rate with a progressive finish.

Allows easy, tool-free adjustment of spring rate.
Includes spring, adjuster, and 5 performance adapters.
Lightweight (highest grade steel allows less material).

See https://sprindex.com/pages/compatibility for fitment details.

Every Sprindex includes a 5 piece Adapter set.
The 2 adapters marked "Fox, Marzocchi, etc" may also fit other brands that have a coil inner diameter of about 35.5 to 36mm.

The 2 adapters marked "DVO, Cane Creek, X-Fusion, etc" may also fit Ohlins an other brands have have a coil inner diameter of about 36.2 to 37mm

Rockshox, Formula Mod, and EXT do not require any Performance Adapters but we recommend using the Performance Washer Adapter (included).
Note, Sprindex fits too tightly to EXT sometimes so we do not actually recommend Sprindex for it. The inner diameter without adapter is 38.3mm
