    Out of my mind, back in a moment.
    Ok, I've specced it out as the following:

    06 King Kikapu
    Mavic wheels and hubs (trade in at shop)
    SRAM X9 or XO shifters and an X0 rear derailleur
    (From my hardtail, I'll swap the brakes, bars, and fork from the King.)
    Fox Talas R fork off my Trek
    Juicy 7's off my Trek and add carbon levers
    Monkey Lite bars off my Trek
    Saddle off my trek.
    Possibly some carbon fibre seatpost?

    Now, I'm also looking at an FSA Mega Exo BB and carbon crank setup. Problem is, if I'm going to spend a load of money on a set of cranks, I'd almost want a chainring guard on it as well to protect the investment. Would it be feasible to run two rings for XC use (maybe a 32 or so tooth ring and something like a 38?) and a bash guard or should I look into something like the Salsa chainring guard?

    Thanks builders, I appreciate it.

    I know that there are people you run a 36-22 front ring set-up when using a DRS system. I actually ran that gear ratio for a while on my prophet, then went back to a traditional 44-32-22 on it. I found that the 44 tooth ring on the front allowed me to descend faster, due to the ability to pedal at higher speeds.

    What is your goal with the bash? To save the rings, cause it won't help with the crank arms. I'm going to assume that the cost of replacing a 44 tooth ring would be much lower than replacing one of those crank arms. I wouldn't worry about the bash too much for XC riding, but thats just my .02.

    I run a 36/22 with and e13 DRS. I really don't miss the big ring as I do mostly trail riding and never really have a long decent.

    You can run a 38 or 40t with a 26 or 28t small ring and an outer guard. With a 30t rear cassette granny that should be more than enough to get up any hills. You'll have to special order the small ring, but I know someone makes them. As for a guard...Evil/E-13 looks nice.

    Carbon post....depends on if you are running a lot of seat post or not. I would say no and go with a Thompson (Elite?). Light weight, strong, etc.

    If you want a CF post though go with a Bontrager Race X Lite. Not stupidly light, made by Trek and put under an insane amount of load during product testing. I won't quote numbers as I don't remember them, but basically they would hit it so hard that it would flex about half an inch and they could do this several 10,000 times without it breaking. It also has the best seat head that I've tried. I run one on my road bike, but have a Thomspon on my MTB as I run a lot of exposed seat post.

    Double ring setup is cool and makes for a nice chain line.

    Actually, how will an ISIS BB compare to one of the new outboard BBs? I could get an ISIS and older FSA isis carbon crankset for about half the price of the new ones.

    Any thoughts on a good front derailleur? Something light, stong, responsive?

    If it's half price, I'd go with an ISIS setup.


    As far as a Ft. der. goes, I'd say LX or XT as there isn't a huge difference between front derailleurs.

    Watchin' you. Writing it all down.
    Are you tearing up front chain rings now hitting stuff? If not I wouldn't worry about it. If you do ding one they are easy enough to bend back and it allows you to keep 3 chain rings.

    The outboard bearings are a better setup all the way around. Unless you are on some sort of anti shimano kick, the XT cranks offer great value and the weight is not that much more than what you are looking to get.

    Carbon levers... unless the shape is better for you and the price is right I'm not sure about the value in that upgrade.

    As for the seatpost, if you aren't too sure about the carbon post, a thomson is a nobrainer.

    An LX front derailleur will be just fine for a very long time.

    Which mavic wheelset are you looking at?

    But they look so pimp ;) The carbon levers do feel better on the Juicy 7s...although that's probably a personal preference.

    Like DRB mentioned, the new XT cranks are an excellent value. Acadian has them on his bike and he really likes the way it performs.

    For a front derailleur, have you looked at the SRAM x-gen? They are not too expensive....

    Not really an issue against shimano, but I'm not sure that their BB will fit the 68mm Kona BB. If I can get a MegaEXO setup from FSA for it for a decent price, I'd go that route I think.

    Thompson post, check.

    No advantage in going with anything better then an LX front? What about changing the shifters to sram X9 or X0s? That would most likely give a better feel anyway (and the Sram rear derailleursseem to be stronger anyway).

    As for wheels, they're the new ones out from mavic...supposedly only 200 bucks a pair? Can't remember the name of them.

    I think they clamp too high to be used with a FS rig. I could be wrong though.

    Not sure. Might be a decent idea to look into that.

    Although, A lot of the parts could be easily swapped at market value by the shop I plan to order from, so that would easily offset the cost.

    The XT bb will fit fine. It comes with these spacers that will get it to the right chain line without issue. If you can get the FSA cheap then cool. But if not, I'd save the coin on the crank and put them into the next wheelset up you can afford. Wheels make or break a bike.

    If you look at the XT and LX, they are virtually the same. I have never had a single problem with an LX front derailleur. The only reason my current bike doesn't have one is that it didn't come with the kit. If I was piecing it, I be rocking another LX derailleur.

    I have limited time on SRAM shifting so I can't much comment. The only thing I will say is find a bike with X9 and see if the positioning works for you, if it does I'm not sure I jump to the X0.

    Not sure which set but most of the Mavic wheels in the lower price ranges are heavy. As I said it might be worthwhile to reconsider spending less elsewhere and putting it into some really kick a$$ wheels. Or if you can drop some more cash into the build this is where it should go.

    What wheelset would you recommend then that won't break the bank?

    i know the mavic 517 rims (721 now i think?) build up nicely, and quite cheaply, good weight too.

    I'll keep them in mind.

    Anything other than those?

    So are you going to run a bashguard? I think I'd agree with DRB on this one. Riding normal trails I rarely end up hitting my rings on anything with enough force to damage anything. I ride a VT for trails and use a regular 22-32-42 setup. I could not imagine riding the bike without a big ring. It would be a real pain.

    As for wheels, I almost always recommend the same stuff- reliable hubs (Hadley, Hope, Shimano, DT-Swiss) built by an experienced mechanic on good rims (usually Mavic). If you look around a bit, you can find some deals. I used mtbr and this site and run a Mavic Crossroc UST front and an 819/Hadley rear. It has been basically flawless- no problems, very littel truing needed, only one flat (running Conti tubeless tires). Mavic prebuilt sets are good too but I think that at the lower price points, handbuilt are better. I sure as hell wouldn't mind having a set of Crossmax XL or SLs though.
