Title: Noleen NR4
Post by: Proflexman on June 17, 2003, 07:29:21 am

I have one of these on my beastie boy however when i bought it i did not know at what setting it should be at.
So i downloaded a tech sheet from the K2 site and when i phoned CVI up and said that i thought i had the wrong spring they explained i had calculated it wrong and told me to do it their way so i did however my local shop said no that is wrong.
So what do i do who's advice do i take.
The rear spring is a NR 175-600 and i weigh in at 15 stone or 210 pounds.
I measured the length of the spring with it only just nipped up and without anything on the bike and then i had someone measure it whilst i was sitting on it and then i calculated the diff between the two and the sag was 25 mm.
Can anyone surgest what i should do as i feel the spring i have is too light for me.

Definitely go with CVI's advice, they specialise with noleen and K2 products, and they always get excellent reviews in mag reports, they also let you  try a spring and if your not happy they will refund you or  let you try another until your happy can't say fairer than that.Simon. P.S you should be running 8mm sag measured at the shock (20% of the shock shaft stroke) with very little pre-load, your spring seems to be to soft.[smiley=laughing.gif]

190 - 230 pounds in body weight shows a 700 lb spring rate for the beast

My guess is that the K2 spring rates are set to control "bob" rather than give the best overall ride-in other words they went stiffer than required in order to keep riders/writers from too much mention of K2 bobbing.  Unless you're an XC racer type I'd go with the lighter spring if you're close to suggested max/min.

Along the same lines K2 said one years lineup had 4 point something inches of rear travel when the actually had 5.  This was because industry/magazine thinking was that 5 was too much for efficient trail bikes.

 :PI contacted CVI about the rear shock and on their advice i bought a 750 spring.
Its now fitted to the bike and the rear end is alot better, firmer though i have to try it out on repetitive fast bumps to see how things are.
Otherwise i can recomend speaking to CVI about your shocks, any shocks.
