Some quick observations
1/ Chainring is heavy for a 32t (or is it a spiderless?) typically 40-45g.
2/ Eagle setup is heavier than a decent 1x11

Otherwise everything is about on the money for the style/riding type of bike I'd say.

Its a Trail bike. 150mm in front and 127mm in rear travel. Its a Yeti Sb5 Turq. Going to go in this week and order it at LBS for birthday present to myself.

THe only thing i can think of to lighten it is.

Change pedals to Time atac MX12 - 320g
Change saddle to WTB Volt carbon - 157g
Change rims to Enve M60 - 748g
And change brake rotor bolts and brake clamps bolts to titanium bolts which will save around 30g

Xpedo M-Force 8 Ti are 214g.
Eagle setup is heavier than a decent 1x11

Also this, e*13 TRS 9-46 has greater range than Eagle, is lighter (307g) and you can use it with RD-M9000, which at 221g is againt lighter than SRAM counterpart.
Grips - Ergon GE1 Slim Black - 103g

Grips are too of a personal choice, but foam ones will save you another 50-90g.

You are going to love the Yeti. I built up this 2016 Yeti SB5c at 21.5 lbs. for XC & XC Marathon races. For trail riding I just change the pedals & tires.

Honestly, you've got an ace set-up there, and every gram saved will probably cost some performance. If it was my bike, here is what I would change:
- Saddle to a Tune Speedneedle. However, saddle fit is highly individual, so might not suit you. Still, there are many lightweight saddle options which would help you lose around 100 grams.
- Pedals to some Xpedo M-Force 8. Their lightest model (215 g) has Ti axles and a weight limit very close to you weight, so for some peace of mind, I would go for the M-Force 8 with CroMo axles (260 g). http://www.xpedo.com/products/pedals/mt ... force-8-cr
- The Eagle groupset is obviously quite a bit heavier than an 1x11. However, I would feel reluctant removing it if I already had it on the bike.
- I would toss the Maguras and try the TrickStuff Piccolas. Seem to be both powerful and seriously light (and seriously expensive). Would save you around 150-160 g on your current brakes. Besides, this all seems quite heavy: Brakes Mounting Hardware (Rotor bolts and clamp bolts) - 48g; Magura Shiftmix Clamps - 36g; Magura QM40 Front adaptor 180mm - 38g
- I would put on some ESI Chunky grips at 60 grams, losing 43 grams. I love the ESIs, but YMMV.

That's my take on loosing weight without sacrificing performance. Of course you could find lighter rims, hubs etc, but they won't be as sturdy as the Enve ones.

While Ralphs are great tires, they have no business on the front end of a 150/127mm trail bike. Sorry.

Really, they don't belong on any bike over 120mm. Great for their designed application, but not for this one.

Nobby Nic? Sure.
