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.

Okay, after I redid it I got the same answer. I'm just as confused as you are as to why the diagram they gave us, which positions the rear axle below the chainstay pivot, is apparently drawn incorrectly according to the answer key. The diagram you sketched is correct according to the answer key, but at this point, I think it's probably fine to double-check with the professor to see if the answer key is wrong.

The dimensions aren’t well drawn to be honest. What I did there is a graphical approximation of leverage ratio by the way. If you dimension the shock ever so slightly shorter (in this case 0.01 mm) and then look at the vertical displacement of the rear axle and divide that number by the difference in shock length it gives you...

This is what you get if you only account for the y component of the reaction force at the seat stay. If the rear axle were to be horizontal from the chain stay pivot that assumption holds, but in the case of it being offset, both the x and y components of the force contribute to the moment.

The moment about the chain stay due to weight is correct at 82.5*465. The remainder of that equation needs to be for the seat stay. So you’d see things like 175/459.62 (similar triangles like you are using but for the seat stay).

Ahh, I forgot about the force vector being along the axis that connects the two pinned points. That's my bad. Thanks to your help, I actually have an answer now, which is a significant improvement compared to ~an hour earlier. I didn't expect you to reply at all since I posted this thread half jokingly, but I honestly appreciate it 👍

The rear wheel force would be half the rider weight as described here. In the case of a member that’s pinned on both sides, the force vector is along the axis that connects the two pinned points. So the shock can only experience tension/compression. That makes the second question about the direction of the force through the shock easy. The...

Start by finding the moment due to rider weight about the chainstay pivot on the front triangle. Since this is static, the sum of the moments about that point must be zero. This will allow you to find the reaction force at the seat stay. Remember since everything is pinned, the force can only be along the axis of that...

They didn't dimension the other lip... it could be 6.5 mm wide. But not making dumb machine shop assumptions, it's approximately 36.5 mm wide on account of that 3.5 mm dimension actually being at a slight angle. I took the profile and traced it on my computer really quick. Going off the 30 mm dimension being correct, all the other...

I would depend on the trails. There are plenty of more XC oriented places around here where climbing out of the saddle is frequent.

I haven't looked at the V10 in depth enough to compare the flip chip settings, but with most Santa Cruz frames the flip chip makes the bike ever so slightly more progressive in the low setting. Usually it's a small enough amount where I'd say most people wouldn't really notice it. But again, haven't looked at the V10 flip chips...

You might be able to notice the affects of anti-squat more when seated, but standing and pedaling is where most people need more of it. Pedaling technique could be debated, but most move up and down quite a bit when pedaling while standing. That load adds to the squat that would be experienced from accelerations forces alone.

Precisely. Theoretically at 100% anti-squat the sum of the moments about the IC is zero so the suspension neither squats nor rises. In reality, I think you want a little more than that to counter center of mass bobbing up and down. That's a hard one to quantify though. You could argue that for a bike that's geared towards fire...

Changing to a linkage driven single pivot similar to Kona from a Horst setup dramatically increases anti-rise at start of travel and it drops more over full travel. Comparatively, the changes Commencal has made barely change anything. I would hazard to guess that Commencal is more after changes in compliance than kinematics.

Going to the more progressive linkage will get you a softer off the top feel. You'll likely want to go up in spring rate to keep sag similar. In my mind, the whole starting ratio thing is more of a question of whether or not spring rates will work out for people or not. If you say that you want...
