Thanks for the confirmation, that def makes me feel better.
Are We Getting A New Cannondale Supersix?
Moderator: robbosmans
I was looking at a SupserSix Evo 105 for 2600€ but it's a 2020 model so I assume it doesn't have the metal platerides4beer wrote: ↑Mon May 10, 2021 3:59 amThanks! No issues so far, about 2,600 miles on this setup. Haven't had any issues with the headtube either thankfully. I read somewhere that the 2021 frames have metal plates to help with the impact, not sure if that's true tho.

I wouldn't stress too much on this issue, in the instance where the metal "spike" has had that much force to rip through the carbon I imagine it would have made some pretty significant damage to the top tube as well if it wasn't there. Realistically I don't know what people want from frame manufacturers these days as that isn't an issue you would get from every day riding, you essentially have to be falling off to have this issue
No, it's a serious issue. You don't even need to crash your bike to damage the headtube.
It happened on my my20 supersix and i don't even know how.
Luckily i got my21 replacement. Now i really like the my22 design

I agree, it's a serious issue. I don't want to buy a bike knowing that sooner or later the headtube will start to crack because some engineer wasn't able to do his job properly (I am an engineer too).
People might say that this is not a problem because Cannondale will replace the frame. Well, I have two problems with this kind of "mentality":
- you don't know if the crack is going to appear gradually or if the headtube is going to fail catastrophically (very unlikely, but not impossible)
- you have to send the bike to the shop and wait for the replacement...meaning that you need another bike to keep riding in the meantime

Really? I watched the video and from what I gathered the issue arises if you turn the bars more than the expected range. That range looks to be just under 90degrees so I don't know why you would be turning that far in normal riding conditions?
It's much lower than that, and it doesn't really matter how unloaded it is ... it's a metal blade on carbon - it's going to damage it whatever.Tifosiphil wrote: ↑Tue May 11, 2021 2:12 pmReally?

What can I do about it? I have the smallest mark on one side, which Cannondale basically have said is my fault for turning the handlebars beyond a normal range. So my bike is barely damaged, I can just see a tiny mark. My bike is 17months old and is otherwise immaculate. Am I stuffed here?

HT crack - not visible
We can re-assess if a crack image can be sent over.
Being on the forum should mean they are aware of problems and therefore able to follow the manual and avoid a problem.
For the moment we are unable to progress further.

I think we're all agreed it's not the best design, but once you're aware of the issue it's quite simple to avoid... I've never been that crossed up while riding, and just have a hand on the bars when moving the bike around the house or into the car. Just takes a bit of care.

Exactly, damaging cables is less problem for me than headtube.
I have the my21 now, where there is metal plate inside headtube to make it stronger, but I
1) put some rubber on it to make impact even lighter
2) am still thinking about removing the pin on the fork, because it's useless imo.
It is an issue, it's extremely easy to damage the headtube, you don't even need to crash your bike, you can just hold the bike on the saddle and if steering goes to one side itself, hit the fork limit, you are done.
