2002 Kona Stinky second modification of its geometry with the Marzo 66 tuned to 170mm, a new longer shock (215mm), and a custom dedicated machined part that moves the BB and the master pivot rearward. Rear stroke is now 165mm. Wheelbase 1197mm. Head angle 62.9°.

 Thank you! I was already in love with this bike for many reasons, but I'm very proud of this evolution, and it's quite a revolution on the track for me and my modest skills, my Stinky is still playful but now way more stable and capable, I don't need more for the moment! Well, it's heavy as a tank, but not more than a pro DH bike a couple of years ago, and anyway I prefer to know him indestructible! Next evolution shall be two brand new rims DT EX571, still in 26'' baby!

 Edit: DT EX471 of course, not 571...

 So sick! I have so many questions.

How did you decide your cnc part's bb and main pivot placements?

What are the pre and post modification reach and bb height values?

Have you throw this into linkage design and analyzed the kinematics and have some charts to share? If not I'm going to. Dying to know

 I have to check the numbers, they must be written somewhere or maybe in a deep folder of my hard drive... but I believe that one of my conditions was to keep the BB height (which was already lowered regarding the original bike, thanks to the new lower shock anchor hole).
The main pivot kept the same relative position to the BB if I remember.

For the placements, I've used a CAD software and reproduced a stick model of the bike in his previous configuration, then I played with the possibilities to check bike's angles and rear stroke. The main goal was to match the 66's stroke, which was first in 150mm setting.
As it seemed to be possible without affecting too much the BB height , I expected that was possible to set the 66 in 170mm setting. Then back to CAD, played again, and found that it would be the Graal by simply use a longer shock.

No kinematic study, sorry. It was originally a personal defy, made possible thanks to pandemy and a relative of mine, machinist, that was consequently not particularly busy at work... ^^
The bike has been tested last summer on tracks of Ax-les-Thermes in Pyrénées, and it gave me an entire satisfaction! I'm not skilled enough for big jumps so I can't bet on end stroke progressivity, but in rough and technical terrain, nothing to say, the rear suspension works perfectly for me!

Stay tuned, I'll look for numbers.

 Would you like to get the CAD file directly? IGES format for example?

 So wicked dude! I’d love to try and ride it, I had the 2003 stock stinky. Really cool to see it more modern geo

 This is gorgeous! I love the idea of modernizing old school bikes! Keep it rocking!
