At the moment I'am building up a specialized Demo frame and i'am unsure off the spring rate I should use on the FSR system, I'am only 69 - 70kg and have a 500lb spring, to me this seems a bit heavy, I was going too go down too a 350 lb or 400 lb spring. If I could have the weights off some riders and the pound spring you have would be much appreciated.

Im about the same weight as you, and I'm running a 400pd, im stoked on it with that, but i run my bikes a bit stiffer compared to others.

I'd say jacko is on the money with 400lbs.
I'm a little under 90Kg with a 500lbs
My brother is the same weight as you but runs it very stiff for his weight at 450lbs

Yep much the same here. 68kgs and running 400lbs on a Cane Creek Double barrel though.

Am about to put a 450 on, I weigh about 94 ish I think? I have been running the 400 spring, now I am very interested to see how the 450 goes!

Has my laziness been making my ride not ride as it should? Quite possibly...

Will let you know how the 450 goes!

95kg and 450lbs

I'm a touch over the 100kg mark, I'm running a 475 with the K9 thrust bearing.

His demo is a 2009 yeah?

anyone know if the 2011/12 frames, differ in spring rate need compared to the older model/s?

Thanks for the replys guys, I'am probly gonnalook at a K9 spring in 375lb for myself, should be spot on, alot off people are saying that a "stiffer suspension" dh bikes will handle better tho?

Depends on what you like ... I've gone from semi rigid to plush and I think plush gives me more control and gives me less fatigue.

One of the lads on a Demo that I ride with is currently playing around with weights between 400 & 450 (he is 90kgs) ... he'll prolly go in between 425

I'm 85ish at the moment and recently changed from a 450 spring to a 500. I prefer it. Never had issues with the 450 but I find the extra firmness in the 500 makes it feel a bit livelier.

personal preference... I run my bike very stiff now days... I used to run it soft, but I find I'm alot faster and smother with stiffer suspension, but this may no be the same for you...


Also sorry to hijack your thread but I'm not running a demo at the moment, just considering buying one... I've been looking at the 2012 Demo 8 I... my only concern is with the bike is the Boxxer RC fork... being the entry level boxxer is it likely to blow up or something if its ridden hard and how smooth are they? (my current DH fork is a 2008 888 ATA Wc)
