Are you positive that the bottomout control happens in the damper?keen said:So I read here on a few Mtbr threads the bottomout control is different on the 06' and 07' 36's. I called Fox the other day and inquired about this and was told they have the same dampers ??? What's the real story ? Thanx
I haven't opened an 07, but from what I understand there is a slight difference in the bottom out piston IN THE DAMPER. I think it's a minor thing considering that you could increae bottom out on 06 models if you know what you're doing or if you want to pay Fox for the labor.keen said:So I read here on a few Mtbr threads the bottomout control is different on the 06' and 07' 36's.

The tech. I spoke w/ @ Fox was really open about the damper service. He said if I had any questions about damper service he would be more than happy to answer any questions. I was just curious if there were any improvments for 07' that would make purchasing an 07' over 06' ?C24C said:I haven't opened an 07, but from what I understand there is a slight difference in the bottom out piston IN THE DAMPER.

I weigh 150# all suited up, and only get 18% sag with the light spring in on mine. I forget what color it is, but it's a step below the stock one. I would like to turn up the bottoming resistance though. Havn't done it yet, but I will before the winter's over.TNC said:Don't put too much faith in the Fox coil spring tables. Many of us are running lighter springs than they recommend by a large margin...and yes, I'm talking for use bigger than curb drops...LOL! Many Marz oil bath forks allow some super plush compliance, and the oil level can be used to address bottomout. The same thing can be done on the "Fit" cart in the 36 series. It's just a little harder to access the adjustment, of course.
Interesting. I wonder what position the bottom out adjuster is in in the figures there....mehukatti said:Thanks for that link! Didn't remember that one. Imo, the changes on 36 sound very promising, atleast on paper. Especially this one:
If there was any critique of 2006 36s and 40s it was that they were hungry for full travel. They'd just gobble it up every time they got a chance. Near the end of their travel a small piston would ride into a cylinder, which theoretically increased oil pressure and controlled bottom-outs. But the fit between the piston and cylinder was too loose, and those high oil pressures never happened. Weak sauce.
The new bottom-out control rocks the strong sauce. First, the cylinder is cone-shaped. Second, the piston has an "interference fit," which means it actually touches the inside of the cone. Third, the cone has four sets of holes along its height. When the piston first hits the cone, oil flows through all four ports. Then it squeezes oil through three ports, then two, then just one. The oil pressure builds up gradually, and it builds big.
The old bottom setup generated 80 pounds of bottom-out resistance. The new one generates 600 pounds. HUGE DIFFERENCE! The resistance starts around 1 1/4 inches from the bottom of the stroke and builds smoothly from there. And one more adjustment: The little piston can be moved up or down to engage the cone sooner or later.
I'd like to hear your feedback on the 07'. I just installed the heaviest yellow spring in my 06' . I havn't hit the trails but I can't feel that much of a difference from the green spring. Pisses me off :madman: I called Fox and asked if the 06' & 07' Dampers were the same and they said yes - maybe the tech. was talking thru his arse ???mehukatti said:No, I had it in its default setting till I sold it few weeks ago. I guess I didn't believe that switching it from medium to high would really have enabled me to run the blue spring since the bottoming out was so harsh and obvious. But I guess I can soon find out about the 2007 model since I just sent email to the guy who is selling it. I was originally going for Totem Solo Air, but since I can get the 07 Fox36 for almost the same price that I sold the 06 model, I'm going for it. Talk about a good deal...
Btw, just checked out the fork manual for 07 Fox36 and it seems that they have made changes to the spring recommendation table. Now the recommendations intersect for different springs, ie. now for example my weight (~176lbs with gear) matches with both blue and green spring.
