Awesome modded EVO frame!

[Mak90]

So i picked up one of the sweet old Noleen DH forks a while back, and I emailed k2 asking for some information about it. Well, I"ll post something else about this fork (because its a sweet fork), but the tech I talked to had one, and we got to talking for a while. He eventually showed me this sweet evo he'd been working on! It supposed to mirror the linkage on a motocross bike, moving the shock toward the pivot during compression(more progressive). I guess this is his first prototype, and he's gonna make a steel one later!  Anyway, I knew you guys would think this is awesome-  [smiley=nod.gif]

Heres the link in case it doesnt work:http://idriders.com/proflex/files/mikesbike1.jpg

Is there anyway I could get a copy of any blueprints?  It looks like it would be a sweet project to experement with.

it looks hardcore but i don't understand what the linkage does. the shock and pivot position are about the same as normal. Any engineers out there who can explain?

[debaucherous]

Not an engineer, but a scienist (who spells poorly).  In space the shock moves in relation to the pivot point.  A pivot is a fixed point on the frame, the whole braket moves to allow spring progression... and, if I remember my physic right, the assembly would "self-dampen" (there is probably a scientific word for the phenom)

Look closely at the bottom pivot.  That is the easiest place to see the difference. the schock moves along a curve, not merely pivots.

Over simplified, by a guy who is a chemist, not an engineer.

is it me or does that swing arm look longer then a normal evo   and check out the dropouts

I suppose the linkage would change the rate of the linkage towards a falling rate.  But doesn't it look like the shock mount would move away from the pivot upon compression rather than towards it?
