Mono Spring Question

[bjniceguy]

when you adjust the spring on the rear suspension of an apex, does tighter (less sag) add to ski pressure or reduce it? I am talking about normal riding, not ski lift at transfer.
On an old suspension if you tightened the spring on the front of the rear suspension, you lessened the ski pressure. Not sure on these.

I do believe it seems to lessen the ski pressure as the front of the rear skid has to become stiffer, thus lifting the front of the sled?? While i experimented with mine it seemed to have less ski pressure the more i turned up the rear.

Knowing that a lot of the darting issues are tied to snow conditions, I am trying to decide if the darting is tied to too much ski pressure when you let off. Possibly running at minumum sag rather than max sag will help some. Perticularly after you get ice build up on rear of sled adding additional weight there.

More preload on mono spring (less sag) increases ski pressure. Set your spring so it sags 40~45mm from zero load (sled hanging or tipped on its side) to siting with your weight on it.

Yes this means you need another person to measure spring when you are on the sled.

40mm = more ski pressure
45mm = less ski pressure

So you are saying 38mm sag would be increased ski pressure.

That is correct. More preload = more ski pressure. Same thing as saying less sag = more ski pressure.

I believe the main reason for this is the front limiter comes into play sooner.

This only seems to affect ski pressure while accelerating or cornering (inside ski lift).

If you go too high at the rear the sled gets tippier so there's sortof a fine line to finding the right amount of preload (around 40mm sag).

the front limiter is loose when you decellerate. That is why I ask about preload. trying to get less ski pressure at decelleration to help with darting & hard turning.
