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.

A good example from the DW patent would be the dependent claim: "4. The compressible linkage suspension system according to claim 1, wherein said the tube of said seat is located behind a damper unit of said suspension system." You instantly differentiate yourself from this if you design a frame with a shock tunnel since the seat tube is no...

It's still just two short links connecting the chainstay to the BB area. One of the links just happens to be mounted to a bearing that's bigger than the link. All DW6 bikes I've seen have the lowermost of the two short links oriented such that the pivot on the front triangle is below the one on the chainstay. The...

You can have an open section that's still great in bending. I beams for example. Torsion is where having a closed out tube is very advantageous. Vertical and horizontal stiffness might be up there, but if the whole rear end is twisting then closing out the cross sections would be a good approach. Carbon on aluminum can be a nightmare...

In the truck world body lifts aren’t super common. Body lifts entail spacing the entire body up from the frame. The common one is preload spacer lifts. Those aren’t great for handling. Down travel is quite important off road so when you decrease that by like 3” it’s not great. A lot of travel for a stock truck is 15”...

Yeah super low leverage ratio easily leads to overdamped. Damping force as felt at the wheel is inversely proportional to leverage ratio squared. This is because you divide wheel speed by leverage ratio to get shock speed and then divide damping force at the shock by leverage ratio to get wheel force. Comparing a 150 and 170 bike both running...

Talking about the math here. Too many unknowns that way since a whole bunch of layouts, technically infinite, can yield more or less the same axle path. It's always an iterative process. To get to the point where the math is reasonable I like to define the start and end point of axle path in CAD and then tweak linkages...

You end up with a bunch of variables. As many as you feel like using really. Changing any dimension causes changes to everything. Knowing what will impact what the most and least is the trick. I always work back from the shock when setting up these equations and end up with something where leverage is a function of three linkage...

@Eae903 my two cents on designing suspension when you are currently studying engineering... I know it takes more time, but you have the math background. Try and work out kinematics outside of linkage. You'll learn a ton. Travel is the integral of leverage curve, leverage is the derivative of axle position (usually in the y axis, but leverage curves can...

Not all pros are anal and picky about their setup and just ride what they get. They are simply fast. Some need to tinker to hell and back. It's the same with average riders, some thinker and some just ride. There is no sense to bemoan people that take a different approach to riding. As long as they articulate their feelings and can defend them rationally, it's all good in my book. Same goes for the Yeti vs. Specialized choice, if you can defend the choice of the Yeti by saying "I want what I want" it's much better than...

For the same design and same loading, stress is the same for the two materials assuming no deflection. Modulus of elasticity is the same for all intents and purposes so when you consider deflection as well it’s still pretty much the same. S-N curve is the quick and easy way to visualize fatigue. For the same stress, 7075 can handle...

Personally I don’t get why companies would be guarded when it comes to their curves from the standpoint of them being copied. I doubt Norco is trying to copy Ibis or the other way around. But even if they were, replicating the geo is easy when you have the time and resources. In regards to unspoken metrics, you can come...

More progressive bikes provide more mid stroke support IF they are sagged the same. What’s often overlooked is the fact that sag at the wheel is increasingly greater than the sag at the shock as a bike gets more progressive. This gives the perception of less mid stroke and riding deep in travel, but is usually just the result of...

I’m not sure I see a downside to progression in the mid 30% range other than small volume air shocks not being good and some people not being able or use full travel. Some of the most well received links we make are around 35%. To date my fastest lap time on predator is on a bike that’s 36%. The...

I would put my money on this coming down to pad retract. The amount of push back they would get if it was next to impossible to get the rotors not to ping off the pads would be a lot more than a stiff lever feel. Throw in a cam with an aggressive motion ratio in the early stroke and...

Definitely going to take a look at them. Hard to say what all will really be possible until can see what the pad retract numbers are. There are some specific things I want to try that could work out quite well knock on wood.

One thing I've been curious about with these, since I haven't gotten a chance to mess with them, is how pad clearance looks. The pistons are quite large and my understanding is the master cylinder piston is at least very similar in size to that of a Code. Assuming the 50% more power thing is correct the math verifies this...

You 100% could. Hard to say what it would do the kinematics without doing some real numbers. With VPP could likely correct it with at least one or two links if it did something funny. Could look something like this… blue is hp black is lp.
