Hi nuke – yes, it's the X3. Got the whole bike for not much more than the frame-only cost, stripped it and rebuilt it – very pleased with it, and the only difference between that frame and the frame-only is the shock. The lockout would be good though (on the RP23 that the frame-only has), but it still works very well in spite of not having it.
Can't recall if my Revs are '07 or '08, but they're the 100 – 130mm ones and they work great at 100mm uphill or down, but at 115 / 120mm it's a wicked bike for XC downhills.
I'm just about 5' 11", shortbread-fanylion and run a medium with a 90mm stem and low rise, wide bars – works well, and gives a good, 'all day' ride position that's comfy but works well on techy stuff too. I did find it a touch twitchier than I thought it might be, with the stock stem and some 100mm Rebas that I put on it to start with, but the shorter stem (it could handle 80 or even 70 I should think) and longer forks have made it more confident on the steps / drops and steeper downhills.
Built up with a short-ish stem, wide bars, longer forks it strikes me as a very good do-it-all bike for most XC stuff. I thoroughly enjoy it.
