We have developed a range of linkages that cater to aggressive riding in rough terrain by delivering more traction and more bottom out resistance. If you ride for the downs, look no further!

All linkages are fully CNC'd right here in Seattle, Washington USA.

CascadeComponents Added a reply to Nerding out on Brakes shall we? Not another tech deraliment

One interesting thing with EPDM that arguably makes it an excellent choice is that it doesn't really melt or anything when it goes over its max temp. It just starts to degrade. This makes it less likely to catastrophically fail, which is a really good thing for brakes. This is a graph I found with a little info on EPDM...

We plumbed a pressure gauge in line with some Code RSCs back in the day. You can easily hit 3000 psi yanking on the lever. That would be hard to see on the trail of course, but pressures are definitely higher than most assume. The bigger limit when it comes to piston temp is more likely to be the seals...

If you are running the fork super stiff you can lower anti-rise since it's not prone to diving. Most WC racers are so that makes sense to me. If you don't run the fork super stiff, weight transfer is accentuated and the bike seesaws when you go on and off the brakes.

Fun fact, leverage ratio is the derivative of Y wheel position with respect to shock position. You can save a lot of time spent doing equations for wheel force knowing that.

A combination of mathematica and 2D sketches in CAD. I write out all the equations using whichever variables I want to change and then use mathematica to solve them and generate plots. Conceptually all the equations are simple. I like doing it this way because it makes you really understand everything that's going on, it's quick to iterate dimensional changes...

In the first image that would be correct in a sense. Hard for me to really tell what’s going on with the second one because there seems to be some transparency turned on.

I don’t have any familiarity with linkage, but anti-rise is a product of the instant center of the member the brake caliper is mounted to. With a split pivot you have two options.

Rulesman Hambini Diaz [I’ve redacted my comment about Dale Stone because I’ve seen two of his videos and that’s not enough to draw an informed conclusion] These are all content creators who seemingly never have anything nice to say about the big companies. According to them, everything’s terrible all the time and they’re the only ones calling it out, the voice crying out in the wilderness. I agree that the big companies do things that suck and that drive me crazy, but if you can’t ever say anything nice about the bigs, even when they notch a win? I have...

Any amount of progression will do it. The million Dollar question is what's the optimal amount? Damping force produced by the shock is proportional to shaft speed. Shaft speed is wheel speed (in terms of displacement from an impact) divided by the leverage ratio. Then damping force as you feel it at the wheel is damping force at the shock...

If you have a progressive leverage curve you effectively get position sensitive damping as you'd feel it at the wheel. HBO makes a ton of sense beyond that when you look at rebound speeds too.

The thing I run into is you can't add compression damping to aid with bottom out without negatively impacting small bump. You could have a high shaft speed because you hucked it to flat or a high shaft speed because you're flying over roots. The shock knows no different. With something pretty linear it's hard, or in some cases impossible...

I wouldn't necessarily say anything less than 30% is unrideable. I mean the Stumpjumper 15 is rideable and that's all of like 12% or 4% if it's a 27.5 rear wheel. That said, i actually maxed out the IMU in the BYB at 16 g when testing the stock Stumpjumper.

This has somehow morphed from talking about undamped spring force and rebound from a flex stay to transmission of vibrations. Very different things. Any frame will transmit vibrations to varying degrees. To figure that out you have to look at natural frequency and then also the frequency of impacts on whatever trail you're riding. I would guess that most flex...

Here is a 2D representation of a Blur rear triangle where the flex stay is converted to standard pivot. The dimensions are meaningless because I didn't scale the image to match anything real. In one image, the shock length is not dimensioned. Because it is not dimensioned, the lines are blue because the sketch isn't fully constrained. In the second...
