    ... and if we just ... Just Another Fatbike Build OFcourse [907-Alfine8]

    Woot!!!

    Finally starting to get parts shipped for my very own build after a year of ogling, dreaming and general lusting for a fatty. Will document it from purchase > complete build. This is my first complete build from frame up FWIW

    Quick Background: I live on a small island with a f%&k load of coast to ride so going IGH is a must, alfine8's have been doing pretty well on fatbikes and have a great price point so that was a no brainer, will have a look at gearing later but I currently ride a 1x9 HT (32-11/32) although I should be running a 30-11/34 there's just so god dam many hills here!

    Right time to go shopping...



    Also here is the link to the google doc which has links to the suppliers/parts I used and associated shipping costs if any.

    That's where I'm at so far, still have to decide on some pedals, a handlebar and a chain.

    Would love some suggestions on my remaining components and any tips on the build up

    I'm not too picky on brand/material of handlebars but let me recommend WIDE! much wider than the 630 you have there. The single best upgrade for my necro pugs was going from the 25mm diameter 625ish skinny POS that surly gives you to a 785mm wide Raceface. Good deals can be found on Jenson. It gets a little dicey through gates and some tree stretches, but it's worth it for the extra control and stability.

    Heres a link to soemthing in the same price range, if you don't like it you can always cut it down...

    It's on a S frame, I'm 5'6" so anything more than 700 is crazy talk I have a 680mm bar ATM and it feels wide. Might try something with more sweep, hearing lots about On-one's Mary bar.

    Hey;

    Here's a fresh cheer for the Mary. I just mounted them on my new-ish Fatty after initially running normal risers on it, and using them on everything else for years. Those don't seem to bother me that much on a full susser, really, but the extra pounding of the rigid fatbike was bothering my wrists. I PURPOSELY went back to a 25.4D to get the flex (extra cushion) back. Perfect. I would be interested in trying wider than the 645s I got, but being that I ride a lot of tight stuff, I'm not unhappy at this width at all.

    The Mary's "odd shape" disappeared when I started riding, and quite fortunately, so did the wrist discomfort!

    Sweet I might just get both, there are a lot of narrow spaces on our local trails and a lot of the adventure riding is more suitable for someone on foot (or a fatbike )

    Mary

    +1 for Mary and the spinoff SOMA Clarence. Went with the soma three years ago after experiencing wrist and elbow pain while riding. Pain disappeared quickly with this bar and minor tweaking of cockpit fit. Just replaced the soma with the mary (wanted 31.8 and a refresh). Mary is slightly narrower and, though I had no complaints with the soma, I find it a little more comfortable.

    Planet X, if you can access them, has the mary on sale for $19.99.

    I'm 5'7" 160 lbs, and on a 16" surly pugsley. I do have an athletic build with about a 42" jacket size and a 31" waist.

    trust me you'll like the width!

    Go with as much carbon as your wallet can handle. My large 9-0-7 came in at 32.5 lbs.

    I plan on picking up a carver carbon fork after xmas when I have some more dough so thats a pretty cheap way to drop almost 500g.

    Pretty stoked with the $+g of the Kore T-Rail Performance Carbon Saddle Combo still have to sit on it though

    Need to pick up some tools.

    Was looking at the torque wrenches on Harbourfreight what size/s will I need? Also I was going to pick up a pipe cutting guide from somewhere?

    Will make a Homemade Headset Press and do something similar for starnut installation.

    Any other specialty tools I'm likely to need that I don't already have for the build?

    2 torque wrenches will handle everything on a bike. A light duty one that tops out somewhere between 60-120 in/lbs and a heavier duty one that tops out around 500 in/lbs or so. I'd steer clear of the Harbor Freight stuff and get something halfway decent.

    shimano nexus chain is a safe bet, especially on the alfine. its 1/8" and galvanized, or anti-corrosion coated. the 45nrth chains are anti-corrosion too. the slug is 1/8", and the willful neglect 8/9 speed would be liter if your cog is 3/32".

    yup no HF as the Q factor is B A D. sears for craftsman is a decent deal.

    I've had good luck with the husky torque wrenches that can be found at Home Depot. If thats too much $$$ go to a pawn shop and look for craftsman. Sears will always exchange them for you no matter how destroyed they are.

    Having never come close to putting a wheel together. I'm having fatbikes make them up for me but as it only comes with the hub I have to pick up a shifter, cog and small parts kit correct?

    Shimano Nexus/Alfine Revoshifter Shift Only
    Shimano Nexus & Alfine Cogs
    Shimano Alfine SG-S501 Small Parts Kit

    Colin pointed out that the alfine8 is a centerlock hub so if i'm using the stock bb7 rotor (G2 Cleansweep) I will need an adapter for 6bolts? Could someone link me the correct one to use with the G2/alfine8 (preferably from CRC or Universal Cycles), thanks.

    Did I forget anything in regards to the rear wheel setup?

    Oh and before I forget does anyone have an idea on what the chainline is likely to come out like....with the raceface atlas (middlering only) 907 frame and the alfine?
    Just curious about whether I need extra spacers or what tricks are used to get it nice and straight.

    Problem Solvers, DT Swiss and Shimano all make centerlock to six bolt adaptors.
    I have had best experiences with the first two brands listed.

    Deity Compound pedals all the way!! Awesome profile, light as hell, strong as hell, and cheap. What more could you want?

    [Edit] Nevermind... I see you bought some already. There goes my chance to influence.

    Da Bomb Bare Bones Flat Pedals | Buy Online | ChainReactionCycles.com

    I was having a really hard time sourcing the compound pedals without getting slammed on international shipping so when I saw these on sale I figured I would just spend a little more.
    They feel/look rock solid, have than low profile and come in at 345g (343g claimed) on my crap kitchen scales. Going to take everything down to work before I build and get weights off the deli scales

    let us know how you like the pedals, it;s the final piece i need for my build, i'm torn because i like clipless. but i want platforms for really cold. it'd be nice to have a 1 sided clipless/platform pedal.

    Too windy to go fishing today but the handlebar from Jenson showed up this morning so I put that on along with the brakes.

    Still can't decide what to do with the Alfine8 cable routing. Probably going to bend the cassette joint and run the green/blue on the wrong side as I really want the cables running up the seat stay > top tube rather than the chain stay > down tube.

    Anyone have any tricks for bending one?

    Both pictures you posted of the frame look as if it is flat black and the fork is gloss black. Did you have the frame repainted?

    The 907-SRD frame comes in either anodized black or painted grey the fork. The fork is gloss black as you say.

    Would get the fork stripped and anodized to match but I will be getting a carbon carver fork early next year so no need to bother.

    Finished! Was a bit unsure about setting up the gears for the alfine8 but it was pretty simple, still want to tweak the cable routing and lenght, but will do it another time.

    Niiice build! That SRD frame gives a very clean drivetrain look IMHO.

    How's the chainline with the Alfine and that RaceFace crank?
    Sprocket and cog combo 32/22 usually gets a reasonable low gear for single speeding at single tracks, how is the Alfine with respect to lower and higher gears compared to the 32/22?

    Chainline looks bang on, cranks didn't need any additional spacers. I can't really comment on the gearing yet (only quick test ride this afternoon) except to say it's my first IGH and the shifting is such a huge improvement. Going from 1-8 in a single twist is awsome. The only thing that would be nice is having a more modern grip shifter to go with the alfine8 the revoshifter is showing it's age.
