Last Saturday I installed the Cogent Dynamics DDCs in the forks of my TW. I also installed the .60 springs that I had purchased from Procycle. I was actually able to ride up and down my sidewalk and hit the 3" rise where two sidewalk sections have separated from each other. The front suspension now responds much more similarly to how my DR650 responded after I installed stiffer springs and DDCs in it. Much less front end dive when you hit the front brake. No bottoming out when you hit a 3" rise at 25mph. Compression is much more uniform.

A few notes.
I was aghast at how little (none) grease there was from the factory on the axle bolts when I removed both front and rear wheels for these suspension upgrades.

Installation of the DDCs is straightforward and easy if you are at all mechanically inclined.

On my 2022 stock TW I removed (as per the service manual) the collar (what we'd normally call a spacer), the retainer (a washer) and the stock spring which is just over 12" long. End to end these components measure about 19 7/8" in length.

The Cogent DDCs and the springs from Procycle together measure almost exactly 19 7/8" in length so the preload ended up the same as stock, albeit on a stiffer, longer spring.

Cogent told me that the oil level should be 160mm so that is what my shocks now have. This is 5wt fork oil.

That's about it. Now I'd jut like spring to arrive!

160mm? That's significantly lower than stock. I'm running 130mm.
True…..but with the DDCs…which sit just on top of the damper rod……there wouldn’t need to be as much oil because the DDCs are always immersed and the damper rod has become meaningless to the equation/operation of the suspension…….so I am told anyway :)
