Hi Ive been designing and fabricating my own line of mountain bikes over the last few years and I have put together a website with photos of my work.

The most recent is the Scissor Jack

Has anyone checked this stuff out yet? Its worth the mouse click. I want your opinions.

I'd be interested in arc path that the rear triangle goes through. Got a diagram of how the rear triangle moves? Say... line drawings of initial, mid, and final positions of the axleshaft, upper pivot, and lower pivot?

What is the shock leverage ratio?

Most importantly.... how does it ride compared to some of the more well known suspension designs?

Ive got all of that just not here at work. Plotted leverage ratios and wheelpaths are both awesome. This one i have not ridden as you can see its not built up yet. Just finished it yesterday trying to rebuild my talas so i can put it together. if it works anything like my other bike then it will be better than anything ive ridden. They have similar numbers so I anticipate it will.

is there really no one on here that this interests?

A floating brake on a "4x" bike is unnecessary.

Its just a name Scissor Jack 4X but I appreciate the input nonetheless. I wanted to try it out on this frame. The linkage design also helps with brake jack but It cant hurt. Plus it takes stress off the non drive side on the rear end and it looks sweet. Theres no reason not to do it I figure.

Great frames. I have one question.

I'm not a suspension guru. There is a wheel travel/shock trave = leverage ratio on Y axis and wheel travel on X axis in this screen shot?

If so, I've thought that there should be as lower value as possible. You frame has 4-4.4 ratio. Is it not too high?

 

[sirknumskullgt]

It starts off high but drops low by the end of it. This is so it feels especially progressive. Its how i wanted it to be.
