Title: Carbon Fatbike build
Post by: TLundberg on July 16, 2014, 09:17:43 AM
Hello everbody!

My first post here...

I'm collecting parts at the moment and this is what I got so far

F-FB02 19" Carbon frame and fork in 3k matt from Speedercycling.com
90mm Carbon rims 3k matt
Carbon handlebar and seatpost in 3k matt
Syncros 90mm stem
Shimano XT brakes
1X10 Shimano XT modified to run 11-42 with part from oneupcomponents.com

Still haven't decided if I should go with the rigid fork or a Rockshox Bluto

Also missing, undecided the following:

Crankset: Raceface Turbine Cinch?
Headset: ??
Saddle and grips ??
Hubs: Hope? Borealis? Other?

Please feel free to give me suggestions :-)

Finally! Some action for the fatty lovers among us! ;D Looking forward to your chiner fat bike build. Been contemplating one of my own for about 2 months now, so will def be following your build thread.

I have the same indecision about the fork.. rigid or the Bluto. I think, due to fat bikes being a bit heavier anyways, and having more cushion in the tyre, that I'm going to go with the rigid fork at first and later on I can sell it and upgrade to the Bluto if I feel it's needed.

As for hubs, Hope is basically the standard, so that will most likely be the route I take.

Yep.. Ready to see some Fat bike builds myself.

In particular though, I'm interested to see how your 42 rear cog performs. Are you going to do the RAD derailleur upgrade?

Yes I do have the RAD upgrade. It will for sure be interesting to se how it performs. 36 to 42 will be a rather big step indeed.

As I have to build the wheels I have to decide to go rigid or bluto before I order the hubs. Does Hope have 150mm front hubs yet?

TL, i also have same frame on order from speedercycling. shoul have it within 2 weeks. mine is 19" with 190mm rear, ud matte. i already have 90mm wheels from nextie. also in ud matte. my build is going to be simmilar to yours.
1x10 with oneup, rad cage, rf nw ring.
xt or slx brakes
rf turbine cinch, i might ponny up for next (will see)
i was going to try chineese bars but the widest they come is 680 which is narrow for me.

also what are you doing for frame protection? stays and downtube? clear tape?
Title: Re: Carbon Fatbike build
Post by: kokosthemakovica on July 20, 2014, 02:24:29 PM
i will eventually get bluto but keep rigid fork as i plan to use the bike with 29" wheels for bike touring, bikepacking, so for this purpose i will be switching to rigid. its lighter and less prone to mechanical while out there in wild.

I'm also interested to hear what guys are using to protect their chiner frames. Fat bike or otherwise.

I'm going to use white carbon 3d helicopter tape (http://www.ebay.nl/itm/261153616922) to protect the stays and downtube and maybe the toptube.

i have used clear helicopter tape on my full susp bike frame. dont remember the gauge though. only issue i had with it was that it yellowed over time. not a big deal on some colors but quite noticeable on white frame.

Here comes a couple of pictures of the carbon parts. I'm really satified with the quality.

Will probably get a chainstay protection of some kind

this is a good product for chain stay protector. i have it on all of my bikes. you can either wrap the entire chain stay as it stretches a bit or just pot a strip over the top of stay.

is handlebar and seatpost from speeder too? is seatpost 31.6mm? i asked them about bars but the widest they could do was 680mm.

Yes, handlebar and seatpost 31,6mm also comes from speeder

Are you using a clutch rear mech? If so then you don't really need a chain stay protector.
Title: Re: Carbon Fatbike build
Post by: Patrick C. on July 29, 2014, 08:48:18 PM
I've got an XT rear der with the clutch, and I still hear the chain slapping on really rough, fast sections when I have the front in the little ring- probably just too much extra chain for it to control all the slap, and it is closer to the chainstay to begin with.  Since I don't always remember to shift back to the big ring at the top of climbs, I put some tape on mine.

has anyone built up the frame yet? i heard rumor that the frame from xmiplay and speedercycling has some issues with rotor and lock ring rubbing?
Title: Re: Carbon Fatbike build
Post by: TLundberg on September 05, 2014, 04:28:48 PM
It's slowly coming together. Still waiting for Raceface Turbine crankset and a few small parts
Title: Re: Carbon Fatbike build
Post by: MTNRCKT on September 05, 2014, 09:51:50 PM
Looking good.


I personally haven't read anything about rubbing issues with this particular frame, but I could've missed it.. Keep as updated if you don't mind bc that's something I'd def want to be confirmed as an issue with specific frames or what.
Title: Re: Carbon Fatbike build
Post by: TLundberg on September 06, 2014, 03:38:03 AM
Yes the rear hub is rubbing against the frame so it needs some modifying to fit
Title: Re: Carbon Fatbike build
Post by: kokosthemakovica on September 08, 2014, 08:31:31 PM
 no rotor rub? what hubs are you using?
Title: Re: Carbon Fatbike build
Post by: dvn on September 09, 2014, 05:59:12 AM
Early editions of this frame have a rear spacing problem. It can be overcome by running a 197mm spaced hub or using spacers and/or machining the rotor mounting area on the hub. Either way, you have to spread the rear dropouts wider to some degree to get the rotor and cassette lockring to clear.

man, how is your build coming along. saw today at mtbr that lou will not fit the rear. what tires are you planning to run?

I have an ebay wheelset built with these hubs. They seem fine so far. Roll nice and smooth. Rear hub pawls are fairly loud if you like that sort of thing. I do.  :)

Any updates? What travel do you have your Bluto set to? From what I was seeing the one fork is 485mm and the other is 470mm - and a Bluto at only 80mm is 491mm, so 100 or 120 would be right out of the question, I'd think.
