Rear shock preload - Glenn has it figured out

[Link]

The bearings are not a new idea. At least in road racing Ohilins has been recomending & selling those for a long time & some Ohilins dealers/gurus will not set up a shock without those in place. So I'm sure they work allowing the spring to rotate with out binding keeps the spring rate more consistaint, but on the asphalt the maint. on those would be yearly. In the dirt that thing might be toast after a few rides.

Check this out.
Hydraulic pre-load adjuster. 15mm of adjustment with a T handle.

Intersting ....
no olins tho.

Just think.
You can have a small pump on the handle bars to change the pre-load on the fly.
Deep sand section coming up........drop that rear end.

My neighbor has one on his BMW road bike (Ohlins) Pretty slick. The Ohlins version has a remote master cyl. on the subframe with a knurled knob you can eaisly grab and turn for adjustment. Great for when he adds bags or a passenger.

Once I got mine where I was happy though, I never touched it.

I guess the ultimate would be fully electronically adjustable suspension but I think I prefer what's cheap and reliable.

Can you post the step-by-step procedure on how to do this.
Thanks.

Pretty easy stuff. The preload is the amount you compress the spring with the adjusting nut/ring. Support the weight of the bike on a stand and back the nut off until it just touches the spring to have zero preload. From that point the more you compress the spring the more preload you have, measured in mm's.

I have my sag set at 100mm.

I'm just wondering about the 125-130mm sag.
Wouldn't that "rake" the front end out too much?

i have the same question - i just set my preload at 10mm, and i get 120mm of sag.. i normally would run around 105-110mm. will 11mm or 12mm of preload get me to 110 and still not sacrifice rebound etc? it's too cold to go out and run it, but i would think 120 would sacrifice turning ability... i've got a 5.4 spring, ltr lowering link, and 195lbs with full gear. also my static sag is 55mm... seems strange to me (i would assume it would be closer to 35mm... ) - does the lowering link affect static sag that much (i would assume it changes the leverage)?
