Sounds like a fun couple of builds. Nice build lists as well. Why did you choose two frames with different BB standards? Surely just more trouble for you. Hope not to start a debate over which one is better just wondering what your thinking is. Can't wait to see the pictures.

This project took a full year of gathering pieces and parts here and there...
I just came with two very good deals on the cranksets at first (Rotor is lighter by approx 35-40g ! ).
Then the framesets followed...
Let's say I'm just happy for now, everything fitted in place just perfectly.
Quality of the frames's finish and tolerances (headset/BB) are very good.

Louis :)

I thought it would be something like that. Always worth being flexible and patient to get a good deal and lighter weight

Ok, a little teaser. Please be indulgent guys :) !!
6.8 kg as it is in the pic. Still missing a few parts ( chain, pedals and front brake installation ) , and also have to dial the bike fit ( missing spacers, top cap, also have 17° stem in hand if the rider position is better):

The builds are now complete !!
I built "Bike 1" race wheels last saturday. I'm very surprised by the weight, 1365g.
Image
I know, I know, the Grifo arrows point backward...it's for better traction ok, ;) ?
Need to put this gem on it, Edco Monoblock cassette 11-32 10S:

Coming back from their maiden ride on sunday:

Bike 1 with training wheels.
The left lever wasn't tightened enough, after many bunny hops practices... I'll have to lift it back up.
Image

Bike 1 front end. Cable routing, with barrel adjuster. The front brake straddle cable was used from another bike.
I'll have to get a new to fit higher on the Wheel.
Image

Bike 2 front end. Notice the "1 X" plug option.
Headest, fork and bearings ( OEM) fit very nicely together.
Image

Bike 2: Ashima brake pads:

Bike 2 Rotor crankset, 36T Wolf Tooth chainring:
Got it from fellow WW member RyanH. I'll have to credit him with a "hero" mention ( as well as everything I bought from him). Superb !!
Image

Bike 1 Sram Force 1 crankset, 38T Raceface chainring:
Image

Bike 1 detail, with the rubber plug in place (Di2 option):
Image

Bike 1 side front. Fork mount canti brake hanger.
Image

Bike 2 rear. Sram X9 Type 2 10S clutch derailleur.
Still missing the chain protector.
Image

All built , Bike 2 with race wheels is 7.27 kg on my cheap hanging scale.
I'll have to weight BIke 1 to see if one twin has an advantage...

Louis :)

CX is all about having fun, here Adèle chasing the leader ( 25 sec. behind, but had time to pose for the photographer ( CREDIT: Paul Schwartz www.paulimage.com )

Spoiled kids, isn't it Geoff ;) ? Florence with her new Giro's on :

On the descending "recovery" portion:

Frankie, I have a pair of Ti spindles I want to install but didn't take the time yet.
Also want to install some Ilink housings I bought a few months ago.

Now the biggest challenge is trying to dial the shifting, between the race and spare wheels...

Louis :)

Get some shims for the cassettes. Can shim them to be in the same place.

Hope my kids never get into cross. Thats 4 bikes, and they are the same age, so limited margin for hand me downs.

Bugger.
