Rear suspension sag setting

Has anyone else measured and set the rear suspension sag?

I weigh about 85Kg in my riding kit. The AT has approximately 220mm of rear wheel travel and I believe the sag should be about 1/3 which is approximately 73mm.

The handbook recommends 7 clicks of pre-load. Starting at 7 clicks I started to increase the pre-load to get 73mm sag. I ended up with it set at 28 clicks.

Anyone else fancy trying this and then pointing out my mistake?

The pre-load knob is quite small and tucked away so not the easiest to adjust.

Sounds about right, I get a preload setting of 10 clicks from the zero position solo and 27 clicks with pillion to get approx 75mm. under sprung for us really but its ok for now.

Just digging around to see what people are doing in terms of suspension setting.
Bit confused by Drago's post.

Does it mean you are 70/80kgs in full gear?

Also, xsilvergs, the pre-load knob is on the left side with a big turn wheel, you said the pre-load knob is small and tucked away, you mean the rebound adjuster? That and the compression adjustment are tucked away good I know.

I'm probably 95kgs in full gear, got the Pre-load set on around 25 clicks, but seems I'm off comparing with xsilvergs' setting (?)

Yes I do think the pre-load knob is small compared with some, I wouldn't say it is easy to use, especially when you want to increase it by 20 clicks. I am aware of the rebound and compression adjusting screws, compression near the top and rebound at the bottom.

The Nitron shock looks nice but I will try to get the damping sorted with the standard spring and if I get close I'll buy the Hyperpro spring. Bike has gone to get it's cold start problem sorted so unable to do any setup.

Yesterday was a day for turning some screws:

One complete turn in (from recommended) on the rear compression damping (yes it sounds a lot).

Two click in (from recommended) on rear rebound damping.

Front tyre pressure 2.2 bar

Rear tyre pressure 2.5 bar

This has given loads more feel with out any discomfort on tarmac roads. I also increased the damping on the front but there are no clicks so will report back when I've finished.

Excellent. Keep us posted.

I've fiddle with the preload in the rear, def much better, gone into 28 clicks from zero.
Front I'm not sure yet, but will do one setting at a time.

I am using 24 clicks from minimum on the spring preload so far riding solo. I am 78kg without riding gear. I have left the front spring preload as set by the shop, what ever that is as it feels fine. I have made small adjustments to damping at both ends to maintain stability. They are a work in progress.
