    White Brothers Snowpack 450 Fork as a temporary solution, will search for a good looking full carbon fork.

    Make sure you get the Chris King Headset with the external lower race, like this:

    Lynskey Stratus-img_9618.jpg

    That frame was designed around a fork with a 475mm a-c height, and the White Brothers (awesome choice, by the way - love the made-in-usa-by-companies-that-still-provide-personalized-customer-service theme) is only 468mm. The external cup gains you 5mm of stack height over the inset bottom race, so it will be just about right.

    A shorter fork wouldn't be the end of the world, but remember that you'll end up with a slightly steeper headtube angle and reduced trail (could actually be good, depending on how and where you ride), a slightly steeper seattube but longer effective reach (assuming you slide the seat back further so that it's in the same position relative to the bottom bracket - again, could be good), and a lower bottom bracket (less good, because it's already quite low to begin with).

    Or, you could plan to run a larger-diameter tire in front than in back, as Lynskey did in their full builds. This is kind of a pet peeve of mine though. I don't get the logic.

    Good luck with the project. Can't wait to see the final results!

    That will be an awsome build but I think "under 25" will be tough. I have an older ti Fatback, with a lighter frame, a lighter fork, a way lighter crank, and wheels that are basically a wash and my bike is just over 25. You will get some, maybe a lot, back with the cockpit bits and you could be a bit lighter on the rest of the parts so maybe it could be done. Lots of room to go lighter in the fork and crank in the future though. In any case anything approaching 25 pounds feels very light on a fatbike because they look like they should weigh more.

    Agree with S your crank and fork are very heavy if you are looking to save weight.

    Hiya, Curious what is your bottom bracket housing width on your frame? Iam looking for an 82mm BB Ti fat frame to build up a 4" off-road adventure bike - that doesn't cost more than my pickup...

    FYI a little info on fork's from the Lynskey website.
    "* Geometry designed around a rigid fork measuring 474.5mm axle to crown length, but with the variety of Fatbike forks currently available, we are finding acceptable A to C lengths being from 445mm to 483mm. Consider that something as simple as modifying the air pressure in a 4.5" or 4.7" tire can alter your frame height moreso than the variances in currently available axle to crown length forks."

    The Lynskey Stratus has a 100mm bb shell.

    Hi, iamkeith

    Thank you for your advice.

    Here is my fork setup.

    White Brothers snowpack 450 (450mm axle-to-crown) + Chris King Inset 7 lower stack height (14mm) = 464mm

    Thanks sryanak & bdundee

    I know it will be tough. Base on my rough calculation, i need to save at least 1000g (my Pug is 12.5kg) to reach 25lbs.

    stratus frame -448g
    snowpack -165g (will change to a full carbon good looking fork and hope to save 400g)

    maybe the key point is the crank but I really hate the big logo of the Next SL

    It's 100mm on this bike.

    Durango bikes makes the Hooey. It's the only fat bike I know of that has an 83mm BB without going custom. It's aluminum, though.

    Ironically, I think that this is on their website because of me. I was pretty excited about buying one when they first came out, but I couldn't identify any off-the-shelf forks that matched the geometry specs (other than the Salsa Enabler, which uses a rear hub and which was one of the things that I wanted to get away from). I peppered them with questions, and the next day that little blurb showed up on the webpage.

    So the thing about the Stratus - and the reason I actually wanted it so badly - is that, other than the adjustable chainstay dimension, it is exactly, to a "T," the same geometry as my 2010 Mukluk that I am so enamored with. You probably recall that, along with the Fatback Ti bikes, Lynskey had built the second-year Ti Mukluks. I tried to get one of those, but Salsa had recalled them all and re-issued them as complete packages only (nothing wrong with the bike - just a marketing decision.)

    I'm sure Lynskey is right - that different a-c lengths will still work, but I'd sure want to test it out before being the guinea pig, throwing down the cash, and building up the frame.

    You should try to get ahold of a first-gen Mukluk to test ride, and see what you think. I could be wrong, but I really think you'll want the longer version of the WB fork.

    Another interesting thing to me is that, as fatbikes become more mainstream and all-purpose trail oriented, they are getting slacker head angles, longer forks, and higher bottom brackets - exactly the opposite of what a shorter fork will do for that frame. (But, again, this is not a criticism of the Stratus - quite the opposite)

    God, don't do that. Stay with the WB, if you can afford it. Who cares if your fork is a tiny bit heavier?! There's huge peace of mind in knowing that it's not a disposable carbon time bomb, will keep it's value, is American-made and, in the unlikely event that you do have an issue, that you can talk to a real person at the factory who will fix it for you.

    I have become not a carbon fan for frames but there have been a ton of people riding carbon forks on their fat bikes for a very long time with very very few problems. Heck I've had various models going on 3 years now pounded hard without fail. Does the WB even qualify as a carbon fork or a carbon wrapped aluminum fork and that is no a little bit of weight that is about a pound of weight difference.

    Op you have a 27.5 pound pugs? That is crazy light!!

    hope you don't crack your lynskey. i know 3 folks that are 160+- lbs that have broken multiple lynskeys. xc types, not huckers. they keep riding them cuz lynskey keeps replacing them. they own other bikes to hold them over till the next frame arrives.

    i've only cracked ti frames. never alu or steel. i've cracked carbon on rock.

    good luck!

    I've owned 6 different Ti frames and have only cracked one on the seat tube. It was an early Fuji Ti. I currently have 3 in the quiver. Titus Ti Motolite, Cove Hummer (built by Lynskey) and a 2014 Salsa Ti Mukluk. Anything can break, hell this is planet Earth, no one gets out alive. Enjoy your Lynskey and keep us posted on the build.
