Looks great.
time to start saving again...
awesome job on the design, looks sick.

I'm just not a fan of the way they machine stuff out. All those ridges make it look like a toy for the blind.
don't worry, thats purely for the prototypes because they had to rush it to get it ready for the bike show, the production legends will all be smoothed out.
but i want the ridges! love the hr giger-esque machining. and nice work guys!
haha you might until you go riding in the mud, then suddenly the frame will weight twice as much and be had to clean... also it addes stress risers to the welds so makes the bike structurally weaker... oh andds a little bit of weight too!
no care. aesthetics over function. give me gratuitous cnc grooves!
hahaha
Haha, I was the one that prompted that question on the blog. Thanks for the clarification though!

hey Colin,
yeah a few people have been asking about it, I guess we should have made it more clear, oh well.

Wow, sick job. I want to try one out now!
Wow. That looks very nice.
I happened to be reading the thread on the new Armageddon. Is it just me or does this design look almost identical to the Trek patent?

Is that susp system same as US7128329 patent, (that is Weagle's pat.) figure 7 in there?? They can market this in the US?
The linkage layout is similar, however read what the claims of DW's patent are - they pertain more to the specific anti-squat curve than pivot or shock location. I don't know enough of the details of the bike to know whether it'd fall under that patent, but I can't rule it out either.
Ok I just read through the patent. Every embodiment described there - as far as IC movement goes - seems to have a particular characteristic of the IC movement, and that is that by the end of the travel, the IC is on the lower link (or has been on the lower link). This is specified in writing in every embodiment, so I'd say it's a fairly important characteristic. Without going into too much detail, I believe this IC movement generally creates a specific characteristic that DW may see as beneficial. However, at no point in the travel of the Banshee does the IC ever reach the lower link. I also don't know what the anti-squat curve of the banshee is, and I'd say this is a contentious point since it can never be agreed upon exactly where the CoM is when pedalling, since riders vary in size and your body moves up and down whilst pedalling anyway.
From this, I am of the opinion that the Banshee doesn't infringe upon that patent (whereas the Giant Maestro system may, as DW has commented upon on the past). I believe there is at least one other dw-link patent though, and I haven't read it so I don't know if it has other things that the Banshee might fall under.
End of the day - this is a much more complex patent than say that Trek/Karpiel issue and there seem to be a number of different things that could cause any bike to fall under the patent. I don't know just how much is required. The claims only really specify the IC movement thing though, and the Banshee is definitely outside that.
You pretty much hit the nail on the head. also... the squat characteristics are quite different, so not infringing in that way either.
To be honest I think it is pretty stupid that you can patent a short link 4 bar linkage design (Its nothing new, been around for hundreds of years) and I don't really like it in this industry all that much as I feel its kinda against the ethos of riding (fair enough if it is something really novel and new, but not something that they are just trying to make money from) I guess that DW just wanted to protect his likage, and I guess its fair enough, but because it wasn't anything all that new as a basi design he had to be very very specific with how he covered the linkage, and hence it can be avoided. Ha, maybe this is my view purely because it means I have to spend a lot of time checking my designs to ensure they don't infring any patents.
is it me or does the head tube angle look a wee bit steep for 65 degrees?
think its due to the axle to crown height on the forks being pretty low on the fox 40's as it is built up.
I love the frame. I'll take one in Full Powder Coat white, Silver Links, No stickers & No Logos w/ a DHX 5.0 or Roco RC World Cup please. 
Thx.
Thx.
The actual SA looks slack, but I think the effective SA is pretty good.
Somewhere right around 70 if I recall correctly!
