I'm sure its a better wheelset than what was stock on mine. After the third broken spoke repair I put the damn thing on ebay and upgraded. The front has been fine, but I guess the back didn't like my 185+ ass pounding it over bumps.
I've had two Pure V Races on my mountain bikes but they both had the stitching come apart eventually. They are really comfy but the older one just got too far undone, other is holding up still for now. Selle Italia saddles seem to hold up really well but I like the Prologo the best of anything I've tried for road comfort.
I hefted a $5k carbon CX bike at a mountain bike event last fall and it was drool worthy. Seriously though, who needs that shit unless you're already sponsored?
My usual riding buddy has the carbon Santa Cruz Tallboy, and the thing is done to the nines - XX1 groupset, best of the best Fox forks/rear/etc, etc. It's an absolutely incredible bike, and he slaughters me in the woods with it, but unfortunately it's a fuckin' XXL so I have no idea how it rides. (He's 6'7) The thing is hilarious, the seatpost comes up almost to my shoulders.
I still crash too much to spend that much on a frameset. If I dent up my alloy Scalpel I don't really care, but if I cracked my carbon MTB I'm pretty sure I'd die a little inside.
