Overview

The Mod is Formula's enduro and all-mountain coil shock with CTS tuning valves and a two-position switch, claimed at 670 g with a 300 lbs/in spring.

The Mod is Formula's coil rear shock family, built around a high-oil-flow damping circuit and a large-volume bladder reservoir for sensitivity and a consistent feel as the shock heats up. Compression character is set with Formula's rider-changeable CTS valves, and a simple polyurethane bump stop handles bottom-outs.

The standard Mod is the enduro and all-mountain version, with a two-position compression switch, major service intervals of 200 hours and home serviceability. A yoke-mount compatible version is available.
