Looking at the SC Superlight I'm amazed at how similar it is to the X57 bikes...I mean, the pivot point is the same...if the swingarm had that taller truss, and the shock mounted differently, it's almost the same frame. Makes me think that the sooner we have a workable, standardized solution for the rear shock adapter the sooner we'll be able to achieve at least some of the advantages of this frame, and the advanced shocks it's able to use.

The 9-series frame would work like the Superlight if a set of rigid braces could be installed into the V-brake bosses and the strut could be clamped into those braces, to make a rigid triangle. Then a strut-to-eyelet adaptor could be attached to the strut where the shock normally attaches, and the shock could connect to the adaptor.

However, I'm not sure it's really worth the effort, because all you'd have then is a funny-looking hacked-together "normal" single-pivot bike. A Pro-Flex wouldn't continue to be a Pro-Flex if it no longer had the shortcomings of its design any more than than if it no longer had the advantages of its design.

Among other things, the strut design on a Pro-Flex gives the swingarm an incredibly linear leverage ratio across the span of shock travel; one of the big disadvantages of most single-pivot bikes is the the way the shock gets tilted towards vertical as the suspension compresses, thus giving the swingarm/triangle an increasing leverage ratio, which makes the suspension "feel" much softer as it compresses. That is probably a bigger factor in the "mushy" feel of older single-pivot bikes than anything else.

I think if someone wants a Superlight, they should just buy a Superlight.

Besides the shock position it's just a 862 in wolfs clothing

Hmmm if i just weld a bracket here

& install a fox shock and fit a longer seatstay im good to go

VOILA!! a superlight without the light

Wonder if a 857 swingarm would fit the old girl to give me a little extra space to squeeze in a bigger shock

I dunno man, but that would be a crazy-long wheelbase. It would be like cornering on a dualie. And I thought my 756 was forward-biased enough already...

Would be good for Hill Climb racing, as long as youve got the legs for it

Anybody want to take some measurement's for me??

Pivot to dropout......?

Pivot to s/arm brace.....?

Seat stay length......?

And B/B to ground height......?

Thank you!!!!

Got my swingarm back from shovelon today. Here's what it looks like with a coat of primer:

Good stuff.

As good as the factory welds, amirite?

Unfortunately the silver paint I got is darker than the original paint. I should've seen that coming, and actually I did, but I figured it would be close enough for government work. I should probably just paint the whole thing, but I'm too excited to go ride it tomorrow, and I don't have a new set of decals anyway. Maybe I'll send it out for a proper paint job this coming winter, when I've nothing better to do with it.

VERY NICE , well done to you both.

that is a great weld (almost said 'cracking' then, but thought better of it

)

Glad you put up the pictures . Thinking of doing this modification too, so I'll have a pro flex for riding in the mud. Looks like great welding shovelon! PF

What's Amirite?

And either you or someone you know is an engineer(government work)?

Amirite == Am I Right, slurred together.

And yes, I'm an engineer working for a defense contractor.

In case anyone's curious, I've learned during my (thus far) short career that "close enough for government work" is ~75%.

More pics!
