Tuning Suspension

[Rontele]

I am running 75% of my body weight in the front on a Nixon, but what is a good air pressure for a 220 lb fool in the rear?

you want about 1/4-1/3 of the travel in sag. prolly 1/4 for you (575 w/ rp3?)

Yes. So would that be like 210psi? I am going to have to get used to that saggy feel. But it must be plush on the down

You have to find that out. Measure the eye to eye of the shock on the bike, then, while sitting on the bike with feet on the pedals (preferably with riding gear on), have someone take the same measurement. Subtract the sitting measurement from the static measurement, and that's your sag. You want your sag to be 1/4 of the useable stroke of the shock. marshal probably knows that figure.

If you have too much sag, increase the air pressure, too little, decrease it.

You should actually try to measure the sag and then divide it by the total stroke of the shock should be in the 20-30% range.

edit - bagtagley wins!

i think the 575 = 2inch stroke
so you should have .5 to .6 inches of sag.

put a ziptie on there if there is no rubber ring.

do not bounce on the bike. climb on carrfully, do not put all of your weight on the rear, rather strat with weight up front as you get on, and transfer your weight backwards till you are centered on the bike and in a comfortable riding position.
