Thank you!! I couldn’t find anything either specifically saying it wouldn’t work but based on the look of the clamp I thought it might.

This reminded me of a puzzling phenomenon. I had a mid-2000s CAAD with carbon fork, ultegra, ksyriums that I picked up for cheap to get into road riding. Decided I liked it, although it was a little too big, and bought a 2023 Supersix Evo 105 in what I’m reasonably sure was the right size. Dialed in the fit and spent some time on it and I am fairly sure I’m 0.5-1mph slower on average on the new bike than on the old one, same effort level, same routes, same tires, same kit. If this persists I may start swapping a power meter back and forth and running more controlled trials this winter.
Landing here a bit late
I am interested in knowing how the longer reach of this handlebar impacted your bike fit? Did you have to go for shorter stem?
I am more interested in those! It looks very good on your bike and considering switching for those soon !

I’m running 36cm pro vibe alloy pursuit bars on Supersix Evo 4 as well. I added the reach of the bike, the stem length and the bar reach together and adjusted the stem length down to account for the extra reach on the bar.
51cm S6 Evo reach + stem + pro vibe alloy pursuit bar reach
378 + 100 + 101 = 579
+ 110 = 589
+ 120 = 599
I went with the 110mm stem so my reach is 7mm longer than my last bike but as the stack is a touch higher it is all good 
Thanks for the explanations!
That is the formula that I had too. From my side, I have at the moment a 100mm and 67mm handlebar reach (super short).
I will keep the same bike. So if I am switching to the Pro Pursuit (101mm reach), I might put a 80mm stem, but there will still be 14mm of extra reach.
I am currently riding a 42cm handlebars. I have read that going narrower is also going longer, so this extra reach might not be a problem but I need to try I guess.
For example, Aerocoach recommend to not change the stem length when mounting their Ornix handlebars with a 91mm reach and 32cm handlebars width
Yes if you are going from a 42cm bar to the 36cm then you can go a bit longer reach.
As the drops are angled rather than vertical the lever hoods will probably a bit narrower than 36cm even.
I would leave the 100mm stem in place and at least try it initially without bar tape. It will almost certainly be too long but at least it will give you confidence that either an 80mm or 90mm stem is right.
Many thanks for your point of view and advice!
The only problem is that at the moment I have a cockpit so I don’t have any stem to test it. But I will figure it out 
The main issue remains getting my hands on one of this bars as they seem to be pretty rare, even in Europe.
Sorry assumed you had got the SuperSix with the stock 100mm stem!
I got the bars through Bikeinn but had to wait a while for them to come back in stock. They certainly seem to sell out quickly in the 36cm size.
Bike Discount in Germany are claiming they will receive more stock on 11/1/25. Good luck with it

I am 179 cm tall. So exactly between 54 and 56 frame. What frame height would you recommend and why? Thanks 
I’m 178cm and riding a 51.
Last few bikes have been slightly lower stack but very similar reach.
Stack
S6 Evo 535
Bond 531
NK1K 527
Reach
S6 Evo 378
Bond 382
NK1K 379
I would either go with the stack/reach that you know is comfortable for you or if your not sure pay a bike fitter. Lot cheaper than ending up with wrong size

I have a 56 and I’m 183 cm. And I think I’m on the low side of seat post exposure. So I’d lean to 54.
The 54 has a slightly longer wheelbase than the 56. I don’t know if they feel different to ride IRL. Someone on the weight weenies thread likely has an opinion about it.

Yeah, for me the issue was that there were no stems available that were the right length. So had to find a longer reach handlebar.
But yes, I always do the math for the reach, bike + handlebar + stem.
I always want to land at around 588-590mm total reach with Shimano levers. And 5-6mm shorter with new SRAM Red.
