I got a shock air pump and read the manual, then adjusted my SID Race suspension fork today. A few questions, the manual (as usual) was rather unclear:

• The top chamber is for 'positive air pressure'. It appears you pump up BOTH sides of the fork for this.

• The lower chamber is for 'negative pressure'. There is only one Schrader valve for this, the bottom of the fork on the opposite side appears to be a dial control making the rebound faster or slower.

What the F is the relationship between 'positive' and 'negative' pressure?

I set the rebound in the middle. I didn't know what the F they were talking about in that stupid manual.

At any rate, after setting the air pressures to roughly what the manual prescribed, the shock feels GREAT, not sloppy like it did from the factory (it didn't have nearly enough air pressure). Love how it feels now, just want to understand how the relative air pressures work. Also, why do you fill both air chambers on the top of the fork and only one on the lower part of the SID?

I don't know about how 'noodly' this fork is compared to other high line race forks. You guys are the experts here. But compared to my 1999 Manitou Carbon this one feels 5x better. More supple response, better feel in every way. No comparison. Doesn't feel noodly to me, but that's like a hopeless Fred saying he has a great road racing bike. I suppose it depends on what you're used to. For me this SID is a huge improvement.
