A while back I purchased an 05' Float R for an older, but mint condition 98' Heckler (built up as a racer but never raced). The Pro Pedal was set too high and I couldn't even get the shock to move unless I used less than 75 psi. So anyway, I sent the shock to PUSH for adjustments and am more than pleased with the difference in performance, although I have a few questions or more like concerns I guess...

I've always ran Cane Creek shocks (AD 12 and Cloud 9 on both old Hecklers and new SL's) in the past and have had very little experience with Fox air shocks but I can definately feel the difference between full air and air/oil. This new setup isn't as smooth or plush as old AD 12 but I do really like the Pro Pedal feature when mashing on the pedals.

However, I noticed with this new Float R rebuild, a certain sound as if there isn't enough oil...almost a dry sucking sound when the shock is rebounding or returing to full extension. Is this normal for PUSH'd shocks? Or Fox Floats in their stock configuration?

I also don't understand why I only need to use 100 psi for proper shock setup (10 mm of sag). SC listed my weight (165 lbs) at 120 psi. Anything over 100 psi and the shock is too stiff and won't achieve the recommended sag. I have the shock bolts torqued at the SC recommended 40 inch pounds so stiction does not seem to be the culprit...everything is pretty smooth when I move the frame through it's travel without any air pressure. I remember reading somewhere in one of these threads that the newer generation of Fox Floats doesn't work to well with older Hecklers...maybe the leverage ratio of my frame is the problem? I do have to mount the shock with the body facing toward the rear and the piston foward because of clearance issues but that has never affected the Cane Creeks I've used in the past.

Anyway, any help on this would be appreciated.

Thanks, Jeff

I have a 99 heckler as well as a 03 SL. I've found 100-105 psi to work well on the heckler with a stock float r ( non pro pedal ) and the SL needs 140 psi. I weigh 165 also,so you seem to be good with your shock psi. Hope this helps.

This does help (as a similar comparison) since I also have a SL and run 140 psi, which led me to ask why the older Heckler only works at 100 psi. I've always ran a Cane Creek on the Heckler with a higher psi before so I wasn't sure what it should be at with the Float R, other than SC's guidelines (of 120 psi).

I do notice the positioning of the shock to be different between the two frames, with the Heckler having the swingarm mount about an inch higher (I also have to mount the Float R with the piston side mounted to the frame since the body won't clear the bottom side of the top tube). That being said, and running a 90 mm fork vs the 110 I run on the Superlight probably contributes to the variable psi even though I'm now running the same make of shock on the two frames.

Thanks again for the response.

Yup, the taller older style swingarm gives the shock more leverage so less psi is needed to do the same work.

Oh, now I get it...different leverage ratios! Thanks again for helping me out.
