Sag questions

[ateick]

I'm working on getting the sag set up properly. New '18 RTX with basic shocks. Looking for a little guidance. Aggressive but by no means expert trail rider - 210lbs.

From what have I read the best way to set the front is to lift the front of sled until the shocks are fully extended and measure the height at a point. Then set the sled down, compress the suspension a few times and measure from the same point. Is 1-2" of sag the acceptable range?

For the rear I believe you lift the rear end and set it down so that the suspension is at its full extended height (track still on ground). Measure and then fully dressed sit on the machine in normal rider position an measure from same point. What is the acceptable sag here? 2"-3"? I am really puzzled with this one because I seem to have a lot of play between the fully extended height and about 2.5" compressed. I don't know how to explain it but I can basically with one finger move the back of the sled up and down 2.5" when it is fully extended. Is this normal? Videos I have watched of others showing how to measure rider sag show resistance from fully extended to fully compressed. They don't have the "play" I seem to have.

Do you by any chance have the front of the sled on something like rollers under the skis? If the front was on rollers it changes the geometry and rear skid saggs badly. Trust me, I thought I had a major issue because the rear skid was sagging real bad over the summer but the guys on here had me remove the rollers under my from skis and everything went back to normal. Just a thought.

No all rollers are out. This video is what I have going on - not my sled of course but you get the idea. Just not sure if its normal. Doesn't seem like it should be to me.

I wish I had that 1.5 of sag with a finger. I agree something is going on. Most of us have put lighter springs in to try getting any sag. Time to pull skid and check/clean everything.

It's new from the dealer. Was like that when I picked it up. I've only put just over 100km on it. Back to the dealership for me I guess.

Wonder if skid was just put in wrong holes?

If is that new I would take it in to dealer.

I had a faulty rear QS3 right out of the box, year 1 had checked and no problem found. Year 2 pulled shocks and sent to Cannondale for rebuilds. Rear skid rebounds as designed now that the shock was rebuilt.

Yea I ran into a few that were bad from factory. But let the dealer figure it out unless your still riding?
