Bought a Countershox/countersycle unit. I haven't ridden it yet so I can't comment on the ride quality, but I have already taken it apart. It appears to have a Brass(?) mass inside which is super tight in the outer tube. I guess this is some sort of friction damping, as the springs are really soft. The marks on the Brass are from when I took it out of the housing. No oil or lubricant inside the unit apart from grease on the springs. Will put it back together and take it for a ride.

Actually very similar to the approach that Downamics talks about using in their Instagram post above. We recorded data from a range of different rides on varying bikes and trails. Merged the data and cleaned it up a little. We used a fast Fourier transform to order the data in a most to least occurrences fashion. Drew conclusions from this and then selected a specific trail that had a range of different speeds, features and conditions in one lap, the kind that, if you were to set up your suspension on, it would yield a solid ball park set up...

11/16/2024 6:44am Nice thanks for the clarification! Could you give more details on the process of deciding which spring to use? Do you have recommendations for trail type and speed? Did you find different riders preferred different set-ups in the same terrain/trail-speed?

Dead Silent, no rattle. Interestingly, ours is sprung much firmer that the counter cycles version in all three frequency set ups we've targeted. It's really cool to see others doing their own data acquisition and analysis of the Countercycle one, I hope ours is put under similar security. The specific frequencies we targeted were derived from a great deal of data collection, Fast Fourier Transfer analysis and GPS comparison. Looking at which frequencies were actually felt as negative at a given instance and which were actually part of the ride characteristics of the chassis. It's clear all the options being...

11/15/2024 12:57am Does anyone know if the the countersycles tmd and the rimpact work the same way? Or is there oil in the Countersycle tmd to dissipate energy?

Hi there! I own a scratch too and I saw you installed an angleset from works. Which one did you get? I really don't understand from their website which one fits... Thanks!
