Air pressure for Sugar 293

Sounds like you've got it - 120# is a good starting point. Also be sure to adjust the rebound to get the rear end to track smoothly. Try a tire pressure of about 5# less than your 26-er. Before riding hard I suggest that you remove the rubber and throw these Bontrager Race wheels on a truing stand to check spoke tension, as mine were loose and the rear uneven. (A 29er with fat rubber will not fit on a Park TS-2). Before re-mounting the tires separate the tubes and add talc to prevent snakebites. Best of luck in your race!

I am currently borrowing my shop owners 2005 sugar 293 and was wondering what the pressure should be in the rear shock? I weigh about 150 to 160 lbs. I saw somewhere on the fisher site that said 75% of the rider weight, but this also was for an '03. This will be my first demo of a 29er, so I'd like the set up to be correct.
Anything else I should note? Tire pressure, Fork set-up. The bike is stock, so I read over the info on the rock shox site for the Reba race. I might race this bike on Wednesday, so any help speeding up my learning curve would be appreciated.

I weigh 190 and I'm running the fox rear shock on my 293 at 100 psi. Any more and it's just way too stiff. I'm also running my Reba way lower than what rock shox recommends, with 110 psi in the positive chamber and 100 psi in the negative. At 160 lbs, I'd try running both shock and fork at around 85-90 psi at the most. For tire pressure, I run around 30 psi front, 34-35 psi rear, with no pinch flats so far.

shock pressure

My 04 292 (and what matter here is the 04 which is different then 03 in the lever ratio)
uses about 80psi in the rear shock for my 185 lbs body weight. Set it according to sag and whatever pressure you end up with is irrelevent. The common wisdom of your body weight should equal the pressure should be taken with a grain of salt as weight and pressure are two different things. A different lever ratio (suspension design) and a different shock cross-section yield different pressure for the same effect.

Thanks

Thanks for the info. I'm doing a ride today to try and get a feel for the bike. My other bikes are shimano rapid rise and this one is SRAM, so it should take some getting used to. Right now I've got the rear shock set to 120, the front 110 over 70 with the flood gate three turns from full clock wise. I've got my shock pump, so I'll probably experiment a bit. What should the sag be on this bike? 25%, 33%, 20%. It did seem stiff with 120# in the rear shock, but that was just me in the basement trying to compress the rear shock, no riding. I think the proof will be if I use most of the travel while on the trail.

my take..

I weigh 185-190 and in order to get 25% sag i ran around 150lbs in the flaot R. With 145psi though i found i got full travel. In the reba in order to get a balance i went with 20% sag which ended up being around 110psi in the pos chamber and then ran 130 psi in the neg..
