Are you sure about the alloy version....?

Checked Cannondale Website and the alloy version seems to be standard 330mm as well. Do you have a link to a 380mm version?

Carbon seatpost is 330mm, alloy is longer with 380mm.
Carbon seatpost has an official minimum insertion of 65mm, alloy 100mm.

I will check tonight. It's shown on the seatpost.
I have replaced the standard alloy seatpost last week for a carbon version and noticed the difference.

Got a chance to look into it.
The measurments you will need is the distance between the 'minimum insertion line' and bottom of saddle rails.
On the carbon version this is: 260mm.
On the alloy version this is: 230mm.

See attached picture for clarification. Top is alloy, bottom is carbon and have been used only with the same saddle height (see white line and carbon paste line)
(please note that I have shortened both seatposts to save weight... this bike is not the lightest :?)

On the photo you can also see the minimum insertion values and a number on the alloy seatpost.
I don't know if this is the partnumber, but its different from any partnumbers since normally they start with K##### as in the manual.

If I already have a limit of 100mm on an aluminum post, its no sense to buy a carbon one, right?

Carbon post can be mounted 30mm higher than alloy.
Its also ~100gr lighter and is a bit more compliant.
(alloy has a full straight rear, where the carbon has a small kink at the top of the rear section, shown from the side).

I noticed though that the alloy is a lot less prone to slippage.

Btw, anyone who needs one, at Sigma they cost €155,-

I had the same problem when I first had the bike. Seriously loud cracking/creaking noises. Cleaned and re-pasted the clamp thing, tried slightly over and under-torquing the bolt, no joy. Then sprayed WD 40 on the screw and silence?!? Been silent ever since. Bizarre :noidea:
I'm confused, which bike has this seat-post clamp creaking issue? Is this the older 2019 SuperSix Evo? Or are we talking about the new 2020?
For me it's the new 2020 version.
I picked up my 2020 Cannondale Supersix Evo force etap this weekend and was told by the mechanic that "if the seat post begins to creak or make noise, Cannondale sells a very specific grease to be used on the clamp"

Congrats on yor new bike!

According to the manual, carbon paste should be applied to the clamp surface facing the seatpost, and grease on other surfaces and thread. Are you referring to the carbon paste or grease?

Remove the tape and apply grease and the noise is gone
Grease instead of the tape? :?:
Would also like to know what you mean, Wenne. The adhesive tape is for fixing the nut to the frame.

The adhesive tape has come loose and is not fixing the nut to the frame any more. Had this issue and the bike shop fixed it by installing a new nut (with new tape).

The tape is a bad solution, with me it does not hold...

And does the nut stay in place (rotation-wise) without the tape?

I was actually surprised that the adhesive tape is relatively small and thin. Would have thought to fix the nut thoroughly you'd need some larger contact surface. But thought the guys must know what they are doing.

And they do stress in the manual that it is INCORRECT if the nut is rotated ... for whatever reasons...

Some small teething problems of a new design I guess.

Does anyone know what bartape comes on the new SS? I've never seen this tape before but I really like it. I can find a Cannondale tape but it doesn't seem to match what is on the bike. The closest I've seen online is the Fabric Knurl and I can't find that locally to see in person.

It's a Cannondale branded tape, there's probably 50 companies that sell a similar knurled textured tape if your local Cannondale dealer doesn't sell it (might be all from the same manufacturer). The Fabric Knurl is one, Arundel Rubber Gecko, but FSA Powertouch looks better as, like the Cannondale one, looks cleaner without any logos in the texture...
