What are you guys getting them down to? I'm not so impressed with mine yet.

I'm running the Anthem X3:

m970 xtr Cranks setup as a 2x10
Easton Haven Carbon bars
2ti egg beaters
Joplin dropper seat post (I'm keeping it because it's worth the weight penalty the way I ride)


Up next in no particular order:

Wheelset
tubeless
Possibly stem (I'm not convinced I'll loose too much here, open to suggestions?)
Rear cassette as the SLX is chunky (though I'm not sure what's the best option value wise)

The biggest weight savers will be your wheelset and tire combo. If you want a fast light wheelset consider the American Classic 29 Tubeless in white. They will match up pretty good with your frame and have excellent build quality and very fast bearings. They are a 1600g wheelset, and if you couple them with Maxxis Ikon EXC which mount up tubeless very easily...you should easily drop 2+ lb. off your bike.

I would go with carbon bars, and maybe a carbon post, new brake rotors, and SRAM PG-1080 cassette. (nearly the same as the XX, but less expensive).

Ofcourse I am talking about $1k upgrade depending on where you shop, but lightening up your bike is not cheap.

The hurtful thing about that is the cost for the upgrades essentially put at the Anthem X 29 One pricepoint :(

The wheelset on the Anthem X29 1 and the 2 use the same rims, and they are not light.

The DT Swiss 350 rear hub on the 1 is a nice touch compared to the Shimano 529 on the 2.

Stiil I think if I were going to spend $3,700 for an Anthem X, I think I would get the 2, sell the stock wheelset and get a really nice wheelset with lighter rims.

On a less important note, I like the color of the 2 better anyway.

It's a little bit odd, but have you guys seen anybody run Cyclocross wheelsets and tires on a 29r.

I think I could get away with the traction loss, but I think this may be worth considering. What kind of weight saving could I see?

If you are riding where a Joplin truly comes in handy, I don't see CX wheels and tires being an asset. . . . YMMV

That is the route I went and with good online prices probably spent about the same as the X1.

Got the X2 and sold off most of it then bought the XTR trail group and Stans Crest wheels.

Mine is about 24.6lbs without being crazy last time I weighed it (720mm wide bars, 180mm discs, standard weight pedals...)

Look up jreinan01 posts on here as well. He is in the process of an awesome X3 build and shooting for 22 or 23lbs I think!

I don't see CX wheels/tires as being a viable option on a FS 29er..or not a realistic one. You can get wheelsets in mtn just as light as any CX...its only the tires that are lighter.

Sweet build Daniel.

Looks like you lost a few GIANT (as in 'humungous) decals along the way too :thumbsup:

just an observation, but how often do you knock over the pet food & water? There is no way I could put it in such a location w/o me or my gf knocking it over. :p

Is your head stack neccissary when running the lefty? I guess the crowns on that Lefty are non adjustable thus the need for all the spacers? Does the lefty come in a tapered headtube if I wanted it. It looks like yours is 1 1/8 upper and lower?

no need for tapered when you have dual crowns. Even DH forks are straight 1+1/8" if they're dual crown, and motorcycle forks are usually only 1"

I wonder if you could machine down a stem to fit in between the frame and top clamp of the lefty? That could drop your controls down 2.5" or so.

When I was looking for bars, I was particularly aware of the rise. Flat bars and 29r are friends. I know one of the design perimeters of the engineers at Giant, or any 29 builder for that matter, was to chop the head tube down to the absolute minimum in order to keep the grips as low as possible. We already have a 1.5" hight disadvantage when it comes to 26rs.
