Fox Racing Shox Float RP3 AVA????
Discussion
I'm actually in the market for an RP23, but a mate of mine offered me one of these brand new. I know it's an older shock but for the price he's offering (about £80 brand new), it's a bargain from my POV.
The only thing is, what does AVA mean!? I can't find anything on Google about this.....ideas?
Cheers,

I THINK its the Adjustable Air volume model.
Unlike a coil spring, an air shock ramps up as it moves through its travel - set it to 100 psi, first half moves easy, but now the pressure inside is 200psi, second half is gonna be harder to move, you see?
This model I think has an adjustable rate to counter this and tune to the bike, many bikes provide a falling or rising curve.
For a falling you want the biggest volume to get the most linear travel.
For a rising rate you want the smallest volume, so the shock pressure ramps up at the end to counter the in.
do you feel that your bike can be setup so that it
1 - Feels lovely and plush at the beginning, but never reaches full travel,
2 - Reaches its full travel the right amount, just a couple of times per ride, but sags far too much when the pressure is set so that this happens
3 - Reaches the full travel the right amount, just a couple of times per ride, but when the pressure is set so that this happens it hardly moves at all on small bumps and has too little sag.
4 - sags the right amount, great small bump performance, but bottoms out over anyhting bigger than a kerb.
If 1+2, its likely to be a rising rate setup, 3+4 maybe a more linear or even falling rate setup.
Of course, lots of bikes have this 'tuned' out using the compression damping circuits also.

Wow, cheers for the comprehensive answer! Most impressed!
I've decided to give it a miss for several reasons. Firstly, it's emerged the shock might have a fault. "He's not sure".
Secondly it sounds like quite an old item. Perhaps already 5 years old and technology has moved forward quite a bit since then.
So I'm back on the market for that RP23. Let me know if you have one for grabs!
