My 9:Zero:7 seems a bit thick.
So far (4th day) I really enjoy this bike. I have a feeling this will be good go to bike and will see plenty of action both on snow and on dirt. I also know that it is going to build huge muscles and I should lose weight like no tomorrow. Weighing in at a portly 37 lbs I am having a hard time understanding where some of you other 907 owners are getting under 30lb and even seen them at 27lbs. How do I shave a few pounds if possible.

So where is the main weight? No looking to weight weenie this thing as I am 6'3 250, but I think it should be able to come down to 31-32 lbs. Thoughts
Tires, tubes, crank and bb
Your tires and the Surly tubes and slime aren't aren't helping you cause. Are your rims holy?
Well, XL frame, nothing to do about that... go tubeless, think about different tires if they meet your trail conditions, 120tpi is lighterish. Your wheels could be drilled out as well. Hydro brakes if you aren't riding in super cold...but I love the mechanical. Bottom line is that without spending oodles of money, it's going to be a pig. I accepted it, and added fenders, bar mitts, rear rack, top tube bag, and a beefy light set up...(I commute every day on it)
Your tubes, with Stan's, probably weigh close to 4lbs. Switching to 120 tpi tires could save another 2 lbs.
You are just not in "fatbike shape" yet. Ride it for a few more weeks and you won't even care about weight.
Thanks for the ideas. Yeah the rims are drilled. I figured it was all tire, tube and slime. will look at tubeless soon but I need to play with it some first. "Fatbike" shape. I love this. Yeah I am way outta "fatbike" shape. But i am looking to gain on this. even with a siadic nerve issue going on I still logged 3 days of rides so far. Cant wait for some snow riding. need to get in better shape for it though. pics soon as my kids stole my cable to download them.
For $20 you can put in Qtubes SL 2.4-2.7 and dump just under two pounds....quick and cheap!
tubes and tires for sure.... almost anything is lighter then a surly tube... and you could drop a fair amount by going 1x9 too
are you using lock on grips?
Yeah, what they said...and my $.02...
#1 - 1x9 - $0 - 1.5lbs
#2 - tubes - $20 - 1.75 lbs- qtubes
#3 - brake rotors - $30 - .25 lbs- ashima
#4 - tires - $300 - 1.25lbs - 120tpi
#5 - fork - $300- 1.5lbs? - carver
#6 - crank/bb - $200 - 1.25lbs - turbine
#7 - cockpit - $150 - .75 lbs - carbon
My medium 907 is at 28lbs. I found the biggest bang for buck with regards to weight to be tubes, grips, rotors, chain, pedals and seat. You'll notice the weight more with rotating parts and the front end, hence tires, tubes, and fork being at the top. 1x9 is a no brainer, IMHO!! Let us know how it turns out!! Good luck!!
I might be able to pull that off in the summer, but my terrain would never allow me to run a 1x9 in the winter.

Some great pointers on bike weight loss.
And I dig the "fatbike shape" comment! These things are a work out.
We lost our snow cover for a few days and I took out my 23 lb 29er. Holy crap....after weeks on the Mukluk....things happen really fast on a light bike. You definatly ride them differently.
My Pugs is pretty heavy - something similar to the OP's rig. I have thought about dropping weight off it, but it would require a lot of $$ and components to be replaced. For beach riding I don't notice the weight because the terrain is pretty flat and for touring trips the bike is loaded with gear so I don't notice it much either.
I don't use my Pugs for straight up traili riding frequently so keeping up with other riders isn't an issue.
I figure I'll just wait until I buy a new fat bike at some juncture and equip it with light parts off the bat when I'm not having to replace existing bits.
I would replace stuff as it wears out, but that bike just keeps rolling and rolling without a compliant so that approach isn't working!
As others have said the wheels/tires/tubes are a good place to work on weight loss. I wouldn't bother going beyond that for now unless you really feel like you are on a mission.
Thanks for this, awesome info. and thanks everyone. Like I said I am not on a mission just would like to drop some weight when the chance comes around. I have though of going tubeless but want to do more reading and the thought of 1x10 has entered my mind, just don't know if I can pull not having granny off. Need to do more research here as well. Guess I have to just do the fun part and get in "Fatshape"

The place the weight savings makes the biggest impact is on internet forums, imo.
Can I ask a potentially silly question: I'm not familiar with the direct mount FDs...does it mount direct to your 907 or to one of those problem solver adapters? I ask because I was thinking of using a direct mount Paul's chain keeper on my 907 with a 1x9 drivetrain - wondering if I need a problem solver adapter.
Sorry for the threadjack.
You will need an adapter either problem solver or 9zero7's version.

'lesn you've got a butt-load of disposable income or a cheap source of really light parts, figure 29-30 pounds isn't bad and leave it at that.
I replaced my surly toobs with regular 2.5" bontragers. THey've worked just fine so far, even on a rolling darryl. That was probably the biggest bang-for-my-buck upgrade I've done.
Also, brand new cranks are expensive as hell. But if you can find an old, light ISIS crank, you can drop some weight. I found a nice, cheap and light Race Face Isis somethingorother on ebay.
My medium 907 came in at 33.99 lbs. without any though to the weight of components, budget took the first priority and using existing parts I had.
Thanks for the info Tiboy.
I have a high 28 pound 907 - getting the weight down to this range requires pretty much all your parts to be pretty light. I have Nate/bud combo on RD, so my other parts were chosen carefully.
I agree on tires and tubes to be the first places to start.
