Suspension Sag and Ride Height
Thought I'd give this a go and post the results be interesting to see what others get if yooz can be bothered.
http://i374.photobucket.com/albums/o...o/Drawing1.jpg Bike is a Z on stock settings and I'm 15st. I was a bit surprised at just how much the bike sags under its own weight and didn't move much with me sat on it.

That looks very similar to the guidance in my Ohlins manual, which I'm yet to attempt.

I've been wondering about fiddling with the spring preload on my Ten over the past few weeks, but feel a bit out of my depth. The bike seems to ride softer than it did 12 months ago when new. I've covered nearly 9,000 miles now, so I guess the springs have softened up?
I assume adding a bit of preload to the springs will help things along a bit, but the question is how much. Based on your details I guess I'm looking at additional compression of just 20mm difference between the bike without me on it, and with me on it. (I'm sure it sags far more than this at the moment). |
I think rider sag is more important then free sag.
Lot of sag on Z model. Is it same on X? I know racing bikes have around 30mm in front and rear of rider sag. Kev fork spacers bring xt closer to this. When you sit on bike for rider sag measuring you should shake the bike (push on handlebar and jump on seat a little :)) to make correct measurement. What is your shock preload adjusting settings? I think you should stiffen it little (Owners manual page 3-13 if you want to). Standard setting is 2, hardest 5. You don't have to have workstand to take first measurement. You can put bike on sidestand and slowly tilt it over sidestand to elevate one wheel of the ground front or rear. Of course second person have to take measurement.

Gonna measure sag on my XTX this weekend to see if there is some difference between Z and X.

Hagon Progessive Fork Springs
Have just had these springs put in my Tenere and the difference is amazing ! . It totally transforms the front end . When you come off the gas it settles right away and doesnt dive like it used too . Also braking is has improved a great deal , and you can feel the road much better . Would highly recommend them . Have also wound the rear preload up to 9 and it feels very solid on the road but not hard .

For the front simply wind in the heads in the fork tops with a 10mm allen key. Bear in mind also that the generic sag adjustment guide is for road bikes, and not long travel trail bikes. If you try and get down to road levels of sag your bike will be very firmly suspended. |
Fair point � I think I'll take the trial and error approach � up the preload a little then go for a ride, up it a bit more and ride again. Start small and try to feel my way to the right setting.

My rear suspension is very hard and looking at the shock it is on position 5 (hardest) setting.
Does anyone have a c-spanner they can lend me if I pay the postage? |
