To help bring this back from the dead, I got my shock in today; just have to drill out the mounting holes on my linkage from 3/8" to 7/16". Also, FedEx bought me another set of wheels and they should be in tomorrow  . |

Got the Fox float DCRV RP23 installed and aired up tonight. Ready for Palo Duro Canyon in the morning .

The Fox shock takes a few hours of riding to break in, so dont be surprised if it feels a bit "sticky" initially.
I run my rear shock pressure at 90% of my body weight(with a full camelback). This will vary depending on the leverage ratio of your suspension, but it could be a good starting point if you do not have a recommended pressure from the manufacturer. I would also suggest taking a shock pump with you on the first couple rides so you can play with it. |

Thanks for the advise; I'm definitely going to invest in a shock pump. Because the leverage ratio is odd with this shock on my bike (because it's quite taller than the original), I'm pretty sure I'll end up running with the pressure set close to the max (max is 200 psi) to keep the shock running in the first air chamber until I hit the big stuff that's suppose to open the second. Here's a new pic with the new wheels. I just have to get to my friend Jorge's place to have him build and weld on an aluminum bracket to hold the rear caliper as my bike originally only came with disc up front and V-brake in the rear. If it didn't look so ugly I'd keep the V-brake in the rear because it's nice and tight, but matching discs is more aesthetically pleasing and I don't have to worry about the pads coming out of adjustment as often, which nearly killed me on the last ride (downhill+no rear brake= endo-ing a lot). I was riding the front wheel downhill a couple times Sarurday, and it wasn't very pleasant.

That rear shock has a rubber band on it so you can tell how far it has traveled.
I always push that up so I can see how far it has moved and just keep it from bottoming |

Yeah I've done that but at the pressure I've been able to put in it (since I don't have a shock pump yet) It's close to bottowing out already on road-sized bumps so it definitely need more pressure. |

Trying to set your shock pressure without a proper shock pump is an exercise in futility...I tried it once
Technically, you want the shock to bottom once in a while. With an air shock the pressure ramps up as the shock goes deeper into its travel, making the effective spring rate stiffer the farther it goes. Unless you have the pressure way too low, you do not get that harsh bottom like you get with a coil spring.
How much initial sag do you get from the suspension just sitting on the bike? |

I have an RP23 on my bike as well, I'm thinkin you're gonna like it!
As you know, a shock pump is a must have.
The sweet spot with my set-up is about 180psi. I weight about 200 lbs with gear and Camelbak for reference.
Of course your bike has different geometry & everyone has their own likes etc.. so experimentation with air pressure & damping is the word.

I'm thinking I'm gonna like it too, and I'm gonna get a shock pump. It'll be a couple weeks before I can make it back out into the canyon anyway. Here's an interesting article on the design of the DCRV RP23 compared to other shOchs.
