    New Fatback Build - from the colorado front range

    2011/2012 has been a great biking year for me. I started riding in 1994 with a Keith Bontrager ( boneshaker) racelite hardtail. I REALLY got into Ibis Ti bikes starting in 2002with my Bow-ti, but I started to notice they collected too much dust and I wasn't riding them.

    For my 40th, my wife bought me a used Mooto-XZ 29er dualie frame. I built it up and rode the hell out of that thing this summer and sold all my Ibis Ti 26" bikes too.( I also sold my Ibis Road 55cm that was too small for me and bought a used 57cm Moots Cross bike..what can I say, I can't stay out of the dirt) I started to realize, if a bike isn't fun to ride..why own it?

    Falling back in love with riding got me night riding for the first time in my life...I love it! But when the snow flew, I still wanted to ride. Solution, studded tires! I purchased a pair of Schwalbe Ice Spiker Pros ( For sale, btw). These worked well on ice but I punched through the snow and lost studs when I hit the dirt.

    THEN..I found Fat Tire bikes here on MTBR. what a revelation! I spend most of my weekends in summit county and the trails we hike with the dogs are usually packed enough that snow shoes are not even needed. After some research I ended up with this...

    2012 FatBack Cycles ride in size 20.



    The Fatback just seemed to be a little better thought out than some of the other options.

    - tapered headtub
    - carbon fork that has more clearance than needed for a BFL
    - perfect set of engineered external bottom bracket cranks
    - replaceable rear deraileur hanger
    - rear rack mounts
    - AWESOME orange anodized finish!
    - great cable routing
    - USA made!

    Greg and Pete were both great to deal with. When I called to order, they told me 1.5 weeks until the frame came in. 2 weeks later, its sitting in my office, packed VERY well! I had several XT parts left over from when I upgraded my MXZ to XTR & I9's last summer to shave some weight. Here is a build list with scale weights I took before bolting everything together...

    2021----Fatback rame w/ BB cups and headset cups installed (thanks Pete!)
    768g ---Fatback Carbon fork w/ race installed
    810g----Fatback/FSA crankset
    67g------FSA headset bearings etc..
    43g -----Salsa Fliplock seat collar
    197g-----Thomson masterpiece 350mm X 30.9 post
    242g ---SellaItalia Ti rail Trans Am saddle ( got one on all 3 of my bikes)
    197g ---FSA SLK 685mm bars
    154g ---FSA OS190 90mm stem
    48g -----FSA compression plug
    206g----ERGO Grips
    287g----XT 10spd shifters
    237g ---XT 10spd rear deraileur
    337g----XT 10spd cassette
    141g ---SRAM bolt on front deraileur
    280g -- XTR 10 spd chain ( I later took 4 links out)
    136g ---Avid 180mm front rotor
    91g ---- Avid 160mm rear rotor
    238g ---Avid XO front brake assembly
    259g--- Avid XO rear brake assembly
    1571g --Rear wheel ( Salsa 170mm hub, Rolling Daryl 80mm rim, straight spokes)
    1283g --Front wheel ( Pauls 135mm hub, Rolling Daryl 80mm rim, straight spokes)
    484gr--- (two) Bontrager 29 X 2.5 tubes
    2850g --(two) Surly BIG FAT LARRY 120 Tpi tires
    65g------ Salsa 170mm Flip Off skewer
    61g ----- Salsa 135mm flip Off skewer
    380g------Shimano M985 pedals

    13454 grams = 29.70lbs



    Impressions...

    WOW! I'm amazed at what this thing can go through. balance your weight and hammer! Two lessons I've learned in the 4hrs I've spent on the bike since completion 48hrs ago.

    A) momentum is key
    B) respect ice covered concrete..

    See you on the trails!

    Went out and took a quick measurement for you. Looks like 4 and 1/8" or 105mm from side wall to side wall at 9 psi hanging in the garage as pictured. Not quite sure how much more I would get with 100's.

    Good question. After all the detail and pre-assembly weights I left out the most important one! Its a new belgium glass, but held one of my favorites and fitting for the snowbike crowd. NEVER SUMMER by Boulder Brewery. See pics for some scientific results.....

    True! speaking of barley, I give you..... KILLER PENGUIN!!! barleywine ale from Boulder Brewery. I bought what DAVCO Liquors had left...three bottles! ( worlds largest liquor store btw). 10% alcohol too

    Good thing I saved it for the super bowl and not the build!

    Nice looking ride, and you guys have some snow to use it on. We need some more.

    forgot to take pics when I loaded it up into the H3 Alpha ( with the fly fishing gear and ski gear) to head up to summit county to ride in the AM...livin' the life. I'll get them for you when I get back.

    we do down here on the front range. Heading to the high country in the AM for some real fun. Now that the hikers have been out local trails should rock for a sunday Am ride when I return.

    Here you go. looks like 1/2"+ clearance on each side. Drive side is couple layers of fancy black E-tape. I hope it helps!

    BTW, I'm running 10spd Shimano dyna-sys 11-36 rear cassette BFL's on 80mm rolling daryl rims and I have NO PROBLEM with chain run on anything. took me a while to dial in the Sram X7 FD but now it rocks!

    thanks for the pictures, think i'm going to run a set of those cranks on my new moon lander. with that kind of clearance i think it will work, those extra spacers and all. building a frame up so not so big and fat. rolling d's with nates and running a 1/10. once again thanks.
