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.

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...

Some food for thought… let’s assume each leg is a cylindrical joint where it can slide linearly and rotate around the axis of said cylinder. A cylindrical joint on its own is equivalent to four points of contact. Six points of contact fully define the position of something in space. Two cylindrical joints is eight points of contact. Both right...

The IC can be under the chain line and chain tension can still pull the suspension up in its travel. The point at which chain tension is neutralized is when the IC is located on a line that intersects the hub and the cranks (idler in the case of an idler bike).

Back on the second page of this thread I posted a diagram depicting the basic forces at play here. In the description of the calculation, the acceleration and chain tension forces are combined into one resultant force. Instead of doing that, both can be analyzed independently. If you say that the sum of the moments created by those two forces...

If you look at how much of the anti-squat is due to chain tension as opposed to axle path, you can get a fair bit more information. The same anti-squat numbers may get you identical seated pedaling, but if the component that’s due to chain tension is different you’ll get different behavior on larger scale compressions.

This is just a guy who has got entirely lost in the weeds. There is no "antisquat theory" that some cabal of bike engineers is pushing. Antisquat can be calculated several ways but the results are always exactly the same. It's a proportion of drive force acting on the shock to weight transfer on the shock. Moving your pivots anywhere on the bike doesn't change this. Pedal-kickback is a much less well defined metric (especially when considering some of the dynamic effects) but the metric is still fundamentally tied to the geometry of a chain-cog system. There is literally nothing...

You can propel any bike with chain growth forwards by bouncing on the pedals. If there's no force on your feet from the chain tension then you should be able to remove your feet from the pedals and bounce and get propelled forwards. That's not happening.

I suspect if you dug into the logic behind the "statics regime" you'd find a fundamental flaw or two. I suspect the logic is that if the IC is on the chain line then chain tension would have no net impact on suspension movement. While this might sound plausible, it has one major flaw... it fails to take into account...

Assuming equal chain growth numbers, no linkage system can make your wheel more likely to roll forward as opposed to rotate the cranks backwards. Chain tension is always resolved by torque at the cranks. This is basically why you are able to pedal a bike. If chain tension didn't require torque at the cranks you'd have something similar to a...

Matt Beer can ride a bike but he has said some bafflingly wrong shit in the past when talking about how bikes work. He's not a great resource for technical stuff IMO. edit: and if you disagree then go and read his "article" about fork offset and compare it to how steering geometry actually works. It's confused and mostly backwards.

I'm sorry, I can't help it: An impact that " forces the rear wheel to rotate forwards" is the same thing as an impact that " deals with chain growth by rotating the pedals backward or stiffening the suspension." In the above diagram, the red force is the impact at the rear wheel. As the rear wheel is being held back by the red impact force, the rear center is growing, which is creating chain tension, which also stiffens the suspension. The suspension can't compress and absorb the bump until the increasing chain tension is relieved, and the chain tension...

What exactly is the concept, though? There's a bit of word salad going on and ride feedback that doesn't make sense. For example " The chassis is very stable, and in a way it's as if the bumps you encounter only affect one wheel at a time. That sounds silly to write down, because that happens on any bike. The...

I'll be straight with you, a lot of the explanations don't make any sense. They kind of give me turbo encabulator vibes. It's impossible to have chain growth and no pedal kickback. The chain tension is always resolved by your feet. No way around that. Whether or not your cranks get rotated by that chain tension or the rear wheel...

I'm going to take a moment to lay out a real tech based reason that a dual shock bike could be useful. Not because I think it's where this bike was going and not because I necessarily think it's a good idea. Just for the fun of it. Each shock has its own leverage curve. You could use this to...

Considering they call them “isolated” pistons and there’s a visible line inboard of the edge of the piston, I think they are using an insert for insulation like a lot of brands are. You can see a very real increase in caliper temp using stainless pistons. I would not want aluminum with no additional insulation.

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...
