These Cogent Drop-in Dynamic Cartridges will vastly improve both the compression and rebound damping of your stock forks. No disassembly of your forks, no drilling of damper rods. Just change the oil to 5w and install the DDCs under the springs and hit the trails.

Stiffer fork springs are required to realize the full benefits of the DDCs. Please call if you have any further questions.

The DDCs are not recommended for use with progressive springs.

Damping rod forks are notorious for being both too harsh yet too easy to bottom. This is the nature of damping rod fixed orifice forks.

Cartridge Emulators make damping rod style forks perform like well-tuned cartridge forks. These tunable valves sit on top of the damping rods and are held in place by the main springs. This makes them both simple to install and completely tunable for all conditions and rider preferences.

Based on the wildly popular Race Tech Suspension Seminars taught by Paul Thede around the world, this step-by-step guide shows riders how to make their bikes handle like the pros. Thede gives the lowdown on all types of suspension, including cartridge and non-cartridge forks as well as dual-chamber and nitrogen-charged shocks.

The three forces of suspension, testing procedures, even the black arts of chassis geometry: Thede explains it all. The book provides step-by-step photos of suspension disassembly and assembly as well as a detailed troubleshooting guide for dirt, street and track.

Use this installation tool from Cogent to be sure that your Cogent Drop-in Dynamic Cartridges are installed correctly. A strong magnet in the end holds the cartridge firmly while you lower it into your fork leg. Then slide the spring over the tool until it holds the DDC down, then gently remove the tool. That simple. Never again question if it is properly seated on the damper rod.

Works equally well for removal when you need to change your fork oil. Also works great with Race Tech Emulators.
