Suspension Settings

So, the Remedy is suddenly riding terrible. It went from being response and wonderful to almost unridable. The back is soft and squshy. The front bounces off every root...


Advice from Fox


Fork
The Fox website has great instruction for the front fork:
http://www.ridefox.com/fox_tech_center/owners_manuals/010/eng/index.html

Here's a summary for my weight:Air Pressure: is in the 90 - 100 psi range. Adjust in 5 psi steps.

Rebound: Has 18 clicks of adjustment. Clockwise is slower.  Start by turning in clockwise all the way (fully in) then back out 12 clicks.I like 10.
.
Lockout: locked out is clockwise. 

Lockout Force: There are 10 clicks of adjustment. All the way clockwise is maximum force. Start all the way clockwise and back off 1 click.

Low Speed Compression: The factory setting is 8 clicks out counterclockwise, from fully in clockwise. I like 4 clicks out from fully clockwise.

Shock
Rear Shock is Fox RP2. It's hard to find info on the RP2. I mean, it says "RP2" on the shock. So why isn't it on the Fox website?

Advice from Trek

Anyway, I found the Trek advice for tuning the Remedy: 


http://www.trekbikes.com/pdf/2010/suspension/remedy.pdf


To summarize that advice:
Trek says: set the front shock to 1/2 weight. Rebound is 10 click out, low speed compression is 4.
Rear shock is bodyweight + 10 lbs, rebound 4 or 5 clicks

When I do this, the front is rock hard and the back is too soft, once I blow through the brain. When I brake, the front completely collapses.


From my LBS

I went out to Outdoor Adventures, because Kevin told me that Brian, the owner, set up his suspension perfectly. I have talked to other local shops about my suspension, but they've never helped me.

I worked with Mark, who took a ton of time with me. I went out in the afternoon on a weekday, when they weren't busy.

We started with sag, not surprisingly. The I had 210lbs in the rear shock and it was close to 50% sag. He bumped that up to 230lbs. Don't forget to set the sag with the pro-pedal all teh way off. Then we did the front. I'm not sure why, but we only allowed a little sag there. But he dropped the front to 70lbs.

We went over rebound again and again in words until I have my own mnemonic: Rebound is in slow. To set it, we dial it all the way in then back off a certain number of clicks. Mark set mine up so it's pretty fast. Maybe faster than I like it. 13 clicks in the front, 4 in the back.

Low speed compression. The point of low speed compression is to let you run the front softer, but not have the brake dive. Mnemonic is in hard. Put it all the way in, the back off 4 clicks.

Front Shock:
Pressure: 70 lbs
Rebound: 13 clicks
Low speed compression: 4

Rear Shock:
Pressure: 230 psi
Rebound: 4 clicks
