Here is my build thread.  Goal was a relatively light weight fat bike I could ride anytime of the year here in New England, so here goes:

After some research I settled on the Carbonspeed 197.  I had emailed with Peter about frames and wheelsets and found him to be quite responsive.  So I ordered the frame, 029 fork, axles, headset and a 68mm carbon wheelset.  Everything arrived about 10 days after ordering.  I have to say I was very impressed with how well everything was packed.  Wheels came in their own box.  It took me a good 15 minutes just to removed the bubble wrap from the frame.  Everything looked great.  No blemishes.  Everything looks finished to a high degree.

My parts list:

Jumbo Jim 4.0 tires tubeless
RaceFace Next SL crank/BB with a 28T
RF Next bars
FSA SL-K stem
FSA SL-K post
XTR brakes/Ice tech rotors
SRAM XX1 shifter/cassette/chain/derailleur
Selle Italia SLR saddle
Time Atac xc-4 pedals

Routing the shifter housing was a slight pain.  Definitely easiest back to front.  Those chainstays are narrow!  Brake line much easier.  Awaiting a stem before cutting the steerer tube.  Wt. 23.4lbs.

Few pics. 

Nice..

Very nice!  Looking forward to seeing pictures of the finished bike.

Bike is done.  Final weight is 23.25 lbs.  Using 4 oz of Stan's in the front and 5 in the back.  Just took it for a quick 5 mile ride on some local trails with about 2-3 inches of powder.  The bike feels incredibly stiff and fast.  Running 8psi in the front and 10 in the back. 

Good job!

23 pounds? That's awesome! Guess I didn't realize fat bikes were getting to such reasonable weights. Congrats and enjoy!

Very light and beautiful build. Congrats!

Quick update:

Bike weighed in at 23.2 final weight.
Raced it this past weekend and am very impressed with the whole bike. 

Hello, just ordered a CS-197 frame, what is the standard rotor sizes (front and Rear) ?

Thanks

Sorry about the photos.  Here you go.

I had a feeling fat bikes could be built in the low 20's.  Question, are you Jumbo Jims the SnakeSkin or LightSkin carcas?  I have been doing some research on fats as I am thinking about his as a next bike.  Seems the Jumbo has the best rolling/weight/traction ratios I could find.  Are you able to confirm this?

Light skin is what I used. Holding up pretty well.  I've been running 6.5 front and 8 back on dirt.  Maybe a pound higher if it's real rocky.
