@ratskid23: Start the ratboy skids for kids initiative - throw all those once-used race tires at local groms.

Polygon Square One EX9 and its R3ACT Suspension - Where it Came From and How it Works
@WaterBear: It's the major factor, yeah. Source? Nah, sorry. There's not a lot of resources on mtb suspension around, it's mostly all motorcycle and car stuff. The best i can suggest is looking through the linkagedesign blog (or downloading the software they use) and seeing how the graphs relate to each other.

Riding Rocky Mountain's 2018 Altitude - First Ride
@Kramz: Why do you think that where the chainstay is mounted has anything to do with the bottom bracket height? The BB on this bike isn't especially low.

Polygon Square One EX9 and its R3ACT Suspension - Where it Came From and How it Works
@R-M-R: Yeah, basically. One is pretty much proportional to the integral of the other. It gets weird when you have a super high or low chainring and pivot (or virtual pivot) compared to the rear axle, which is the advantage of high pivot bikes with idlers - they get the anti-squat without the kickback. If you made a mountain bike with a 20" wheel and a really high bb then it'd also have low kickback for the given anti-squat. Any normal bike with a normal bb height and normal drivetrain? yeah, you're right. And you're right regarding how the link can't do anything special. It can't. And touting that it's revolutionary because the anti-squat is "stable" is funny too. You can get similar "stability" with the lapierre/radon/etc four bar design. Not that a flat anti-squat curve means that the pedalling behavior is stable, or that it's a good thing. tigen already mentioned that it's better to have anti-squat dropping off outside of the pedalling area of the travel, which I agree with.

@blacksim549: I know. For conventional drivetrains though they have a close relationship.

Agreed. Also, with anti-squat that high the kickback is going to be huge.

Is This the New Santa Cruz Nomad?

@poozank: a progressive initial-to-mid stroke will give a supple initial stroke, you've got it backwards. There's two things at play, damping and spring curve. The changing leverage rate affects both. When the leverage ratio starts low, then goes high (regressive, like a nomad) you have more damping at the start of the stroke than in the mid stroke because the shock is moving a lot at the start compared to the middle. This makes it harsh on the top and blowy through the middle. With a low leverage ratio at the start of the stroke your wheel doesn't have very much leverage over the shock, so the spring force is only decreased by a small multiplier at the wheel. Which is why the initial wheel force on a nomad is high and it adds to the harshness. Then the leverage ratio is high in the middle, so the shock force results in a comparatively low force at the wheel through the middle of the stroke. Blowy in the middle.

Uh, I'm critical of the current suspension and I own a nomad 3. I bought it because it's strong and slack, and was one of the few frames in 2015 that had a short enough seat tube while still having an acceptable reach. I didn't buy it for the VPP. It's no secret that it's choppy off the top and wallowy in the middle. Still a great bike, but you've gotta work around the suspension a bit. Driving the shock from the bottom link will make for a much more supple top end and consistent ramp-up through the stroke. Can't wait to give this one a go.
