hey what the heck is the point of a spring like this??? is this a cheap fix for bad shock technology/progessive. ? :think:

it is a progressive wound spring. they are really cool because the spring rate increases deeper you get into the shocks travel. most every motorized vehical uses them.

Err, or is progressive(SPV, CV/T) a cheap fix for bad bike suspension technology???

:D

Those are progressive springs, and as far as I know, they're obsolete, because they're just unnecessary with shock technology nowadays. I've only been into DH for two or three years, but even before the 5th Element came out, I don't remember anyone using those.

Were you only riding for a week before the 5th element came out?

the 5th does predominantly use Ti springs which i suspect are somewhat progressive in nature, as well as have some air assist component to the spring rate.

That stratos was simply too progressive. My bike had 3 sources of "progressivness". Progressive linkages. Progressive spring. And the helix opperates with an air-assist spring, which is progressive by nature of course.

Talk about ramping up way too fast, it was quite harsh due to this, so there can be such a thing as "too much of a good thing" in that sense, still the helix turned a lot of unridable bikes into decent rides (like old falling-rate Y-bikes and such)...

progressive rate spring are anything but obsolete. the reason you don't see many for bikes is bacaue they are difficault to manufacture. as for the ti spring comment, i also bevieve that they have a natural progression but it is very slight, not even coming close to the possible progressiveness of a progressive spring

I remember seeing pictures of peaty and minnaars oranges equipped with with those super trick black box rock shox rear shox with progressive springs. I think the springs may have even been Ti too?

Can somebody explain to me how that works? Does it rely on the softer part binding with itself at a certain point, to achieve an increase in rate somewhere along the line? I can't quite get my head around how it would work if it does something different to that.
