Hi all, I'm in a little of a quandary right now… Here it goes: I've a 2004 Kona Stinky Primo and it comes with a 600 x 2.55" spring. I weigh in at 165lbs w/ my riding gear so I'm wondering if the Vanilla's oversprung?? The most "extreme" stuff I will possibly be doing are just some dirt jumps and nothing more than 5' to flat (ok stop laughing
)
I did a little searching and here's what I came up with:-
Kona's tech manuals recommend a 16mm sag. With about ¼ to ½ turn of the preload ring, I can get about 13mm of sag (about 20% sag from the 63mm/2.5" stroke.)
Is the 3mm shortfall significant??
p.s. Where do I actually start counting the no. of turns on the preload ring?? I assumed that it was the point where I turn the preload ring just sufficiently to stop any vertical free play in the spring along the shock body?? Is that right??
I also search the forums and stumbled upon the following formulas to gauge estimated spring weights:
Method A:
1. Your wt times 0.6 = 165 * 0.6 =99
2. shock stroke times 0.25 = 2.5 * 0.25=0.625
3. rear wheel travel/2 = 7 / 2 =3.5
4. Estimated spring wt = (3.5*99)/0.625 = 555#
(# +/- 50lbs) Recommended for me: 550lbs
Method B:

Recommended for me: 450lbs
The results from the 2 different methods are quite different (550 vs 450)…. So I'm really confused….would really appreciate if you guys could chime in with some advice please. TIA
