Overview

The Mod DH is Formula's downhill-specific coil shock with CTS tuning, in 250 mm and 225 mm trunnion sizes, claimed at 826 g.

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 Mod DH is the downhill-specific version raced from World Cup DH to Red Bull Hardline. It comes in 250 mm standard and 225 mm trunnion lengths, has major service intervals of 200 hours and can be serviced in the pits.
