Finally was able to get out on a ride on my new Jet 9 RDO frame yesterday. Built it up with used parts (except the chain, rear brake line, bottom bracket and front derailleur.) Reba at 120, Sun Ringle Black Flag Pro wheels, all XT drivetrain and brakes. 2.3 Purgatory front and 2.1 Ground Control rear tires. Somewhere around 27 - 28 lbs. I'm not a racer, so I built it on the heavier side for more all-around riding. Fun bike. I've had a bunch of bikes - I honestly cannot remember how many - in my 21 years of biking, but this is my first carbon FS frame. (I had an '11 Jet 9 alloy and a '12 RIP 9 and many other alloy FS frames.) I love the CVA suspension - it pedals great - almost "negative feedback" in that it almost feels like pedaling springs you forward instead of bobbing. My first ride impression is that this thing "corners on rails" - it seems effortless to take tight, twisty lines and tight, linked turns, and you never feel like the bike is going to lose traction. The CVA isn't the plushest suspension design, but for the kind of riding I do, that's the least of my worries.
Speaking of suspension, it is my understanding that the rear shock is to be set generally at 25% sag (on the 2" stroke shock.) Is there a good rule of thumb as to body weight or a good starting PSI? I'm at about 140 psi right now and I weigh about 205 geared up. My two prior Niner FS frames (see above) worked best in that 135 psi range. (I'm a little heavier now, hence the added pressure.) Does 140 psi sound about right? I prefer a firmer rather than softer shock.
