Ibis Mojo Sl Fox Float Rp23 Psi???

eigel said:

What pressure (PSI) are people running in the Float RP23 shock on the Mojo or Mojo SL?

I am 215 lbs 6'3" and have the XL and run the shock at 160 psi to get the correct setup (slack). This is completely different then what is recommended. I also seem to get a lot of fast rebound that I can't seem to adjust from the rear shock but do bottom out the shock a lot during big descents.

Any suggestions? Maybe people could add there PSI and weight and size. I can try graphing it and posting it for others.

6'1" on XL
210-220lbs with gear
210-220 PSI. Fore regular trail riding I run 210, for days with bigger bumps, drops, and jumps I'll run 220.

I also cannot get rebound slow enough. It's close, but I would like 1-2 more clicks slower.

You need to add air to your shock. I think setting sag is the biggest waste of time. Put in some air and see how you like it. Add or remove as you see fit. Bring a shock pump with you on all rides and adjust it on the fly until you get it how you like it. IMO, sag is just a suggestion for a starting point.

I figure I'm about 166-168 fully geared. I run at about 146 psi. all the time. I lost the O-ring off the shock but I know I bottom it. I have never checked sag beyond when I first got the bike. To me, it pedals well, doesn't wallow, doesn't feel harsh at all when I do bottom it....frankly I don't feel the bottom....i just know i do.

About the rebound setting though...I don't have the problems you guys do. I have a huge range of adjustment. If i turned the rebound all the way in, the shock is like molasses. if i turn it all they way out, it borders on bouncy. I think i have it turned in about 4 clicks....but again, i don't really check it. set it and forget it.

It seems to me that people around 150ish or so run pressures about 10-15 lbs lower than their riding weight. But people that are 190+ run pressures about equal to their riding weight if not more so my specs are probably not what you should base your settings on.

I bet you have Propedal engaged when you are setting sag, which isn't correct. PP should be off when setting the sag.

If you did it with PP off, then I have no idea why the pressure is so low to get the desired sag. That is way low compared to other folks around your weight.

I'm ~180 geared up, and I use 165psi. I tried 160, and it was super cushy, but also way too much wallow.

Usually 188lbs geared, I have stayed with the recommended 90% bodyweight so I use 165 -170psi in shock. I can bottom out on a 3' drop to flat.
