this will work, but works even better if i swap the jockeys to shimano profile?
sounds like a plan

 I have no experience with the older ETAP system as I am using the Force AXS derailleur. The newer AXS works with the 36t cassette and has the larger pully profile. Not sure if the older ETAP derailleurs are the same.

Any ideas/suggestions that there is something worth of buying in 1/2 or 1/4 price of the 12s SRAM AXS damn expensive cassette?
I've heard that tha cog spacing is a little bit different than regular and it is not working buttery smooth.

I did a little experimenting with my 12 speed road SRAM setup.

 Shimano chain and everything else SRAM and found it noisy and shifting was OK at best.
 Shimano cassette with the rest SRAM is quite good but only if trimmed gearing near the middle of the cassette.
 Shimano chain+cassette shifting was better but still a bit noisy.
 Shimano chain/derailleur + changing out the derailleur pully wheels made the most difference. Shifting was great and noticeably quieter.

 

 I am using a Shimano cassette on my trainer but have gone back to full SRAM on the bike as I picked up a 10-36 SRAM cassette at a local shop for $150 and the Rival flat top chains are just as cheap locally as the KMC Shimano are on Aliexpress.

 I am swapping in a re waxed chain every 500-800 km to get the most life out of the parts.

 I have tried all the above scenarios for a couple weeks each except for the Shimano chain alone as I was not happy with it.

My body just seems to get along so well with Pinarello geometry.

I have had 2 genuine ones in the past and still have my old race bike from 2000. I have never had anything more comfortable geometry wise. Would LOVE to see someone start making the "X" style frame. I hear those are excellent.

For those interested, this frame as well as another new one is listed on Geometry Geeks.

 After some thinking I think this is what mine will look like. A bit of an homage bike if you will.
 Please don't roast my photoshop skills LOL

 I am ordering this frame as well. I will be painting mine - just need to come up with an idea. I just did a g056, have my old Pinarello in prep and just stripped a 68' Grandis Superleggera. My brain is hurting a bit LOL.  Looking forward to your build.

I don't want to sound like a coolaid drinker, but i've rebuilt my rim supersix hi mod with 25mm (expensive) tubulars, whole bike weighs 6kg, and done a couple of rides on it, after riding my LT268 for the whole season. It feels bad descending because it's jittery AF (tyres), it feels bad on bad tarmac (tyres), i'm not materially faster uphill (comparing max efforts). That frame is the himod model from 2015,

 I have the same bike with probably 30,000 km on it (bought new in 2014 full w/full Ultegra). My climbing times were better  than compared to now as well as my sprint but it is NOWHERE as fast (flats/downhill) as this new g056 with gravelking tires and I am a little heavier and lower FTP  . To be honest it wasn't as fast on flats as my older Pinarello race bike that had 60mm HED tubs.

 I am going to be more road focused though. Just confirmed with Peter on the new road frame they have CS-R01. Chain stay is about 42mm at the tire so my goldylocks 35mm tires should fit !

Everyone has a different taste but imo most people chose ugly paintjobs and spec it with not the best fitting parts. Is a very sporty looking frame with long slammed -17 stem. Also can't agree it's a dog uphill. Mine climbs like a dream. Weight 8.5kg is good for a gravel bike.

 Each to their own opinions I guess. To be fair I ride 80% road so I am comparing climbing with it to my SuperSix, Opera or even a Master I have that was designed in the 80's. Also it's not quite as good climbing as my CrossCheck on or off road but WAY more stable. It's also heavier than yours at about 21lbs with no accessories, 2x SRAM Force AXS and 50mm Elite wheels w/35mm Gravelkings set up tubeless - size large.

  I do love the bike and is my daily rider now and I also like the unique look.

I'm probably going to write-off the G056 and G068. No offense to the owners, but after looking at thread pictures of built frames, I didn't find them visually appealing.

 Very fair point. I built up a g056 for the very reason it didn't look like every other bike out there. It's a bit of a dog going up hills but fast as hell on level gravel/road.
