The actual numbers will vary from rider to rider and setup is in the end all down to personal preference. I�ve found that experimentation is the only way to get it right (I�ve even experimented with both linear and progressive springs at great expense!) However, 1/3 rider/dynamic sag is definitely a really good starting point � work from there.

FWIW, I have a similar suspension setup to you (well at the rear anyway). I am a fairly lightweight 85Kg (in full riding gear). For reference, here�s what I found works�

With Ohlins 60N linear springs in the front I have the preload adjusters set flush on the fork caps giving 70mm of rider sag and 30mm static sag. I have also bought some Teknik valves, but I�m waiting for the cold dark winter nights to fit them.

At the rear (and the front for that matter) I found that to get a progressive spring to work properly you have to err on the side of choosing a higher range of spring rates. With all progressive springs you tend to have to add too much preload to get the static sag right, but as a result you then end up with too little rider sag as you�re effectively squashing out the �soft� part of the spring and going into the high rate part of the spring earlier. Unlike a linear spring, which has the same rate whatever preload you dial in, a progressive spring increases in spring rate the more preload you add, which can cause harshness. Forget about static sag with progressives, and concentrate on getting the dynamic/rider sag right. The key point is to use the minimum amount of preload you can get away with on a progressive, so the spring can react quicker and use its full range of rate/travel and you can maximise the benefits of the �soft� portion of the spring.

Anyway, on the shock I have 10mm of preload (65mm rider sag) set on my Yacugar shock, and I don�t find that you need to add preload when you add luggage/extra weight as the springs progression in rate deals with the extra load. I see that as the main bonus of a progressively sprung shock � less fiddling about with preload with constantly changing loads. I�ve ended up sticking to the suggested 20 clicks out from closed on the rebound after trying everything from +10 to +30.

One tip I can give with the Yacugar shock is to either tape over, or put a blob of Blu-tak in the recess where the grub screw sits in the preload adjuster ring as it gets filled with crud which makes it a nightmare to get the tiny allen key in.

Sounds like a good trip - have fun!
