Just fyi, got a replacement frame for my 2020 SSE after complaining with the dealer (delf-destruction mechanism in headtube).
Cannondale accepted the claim w/o any discussion. Took 4 weeks from complaint to new frame. The frame came "bare bones", i.e. I had to transplant all screws, bearings and plastic parts to the new frame (the other solution offered was to send my bike in, which would have taken weeks).
The new frame indeed has metal inserts at the head tube.

I just dropped my fork out to do a headset service and thought I should check on what the headtube looked like, and suprise, that section is delaminated much like yours. Took some photos and submitted a warranty claim this afternoon, so I'm hoping for an experience much like yours.

Cant get rid of disc squeal on the new build. I'm using ultegra hydraulic callipers and Robert Axle after market thru axles with a brand new Dura Ace rotor. The bike builder thought the disc was slightly warped so trued it yesterday but the noise is back. The callipers have been adjusted too.

Anyone experienced this - could it be the non oem axles/ sticking pistons?!
Use Shimano L03A resin pads, not metal.

Update RE split headtube, cracking and rubbing on my white 2020. I submitted a warranty claim and all due to Cannondale they agreed to replace the frame. However as a 'gesture of goodwill' rather than a warranty replacement, which is all well and good but a bit of a cheap shot, which in plain English means that they aren't accepting responsibility for their crap headtube design and I have to change the components myself. A contrast in response to Specializeds SL7 issue.

It's great they changed the frame, but man it does feel a bit short. The new blue replacement frame has metal reinforcement around the headtube. Cannondale knew this was a problem and changed the design, it's their fault.

I do think this is a design and warranty issue for Cannondale. You can't design a bike that destroys itself from normal use as a bicycle. I may have read the instructions in the manual to *never* turn the bars but I'm not the only person that will contact this bike in its normal life as a bike. Mechanics at the bike shop, storage handlers, train guards, loading onto a car, will all handle it and flop the bars to the side occasionally and crack the headtube I can't control that, it's unreasonable to have that condition for a product.

Fundamentally it has to be fit for purpose (as a bike), the OG Supersix EVO is not. I recommend that any early S6 EVO owner chase up with Cannondale now before the damage gets too bad.

Just as well you did IMO ... that could well have ultimately led to a catastrophic failure eventually.

Quick update on the Hylix post; the quality is pretty good out of the packaging, albeit there are a couple of flaws in the lacquer (but not visible when on the bike). Weight wise 128g, but 117g with 5cm city off. I have not checked to see if there is any more weight to save on the seat clamp parts.

The weight compares to 121g for my tuned cannondale Knot 27 seatpost.

Ridden it once and didn’t feel a discernible difference between the 2 posts, albeit I would assume the Knot would be a little more compliant given the profile at the top.
