headset expander for cannondale superx 2016

[tjalfe]

I got the orange/grey superx with sram and i wanted to change the top cap for an orange from kustomcap. So far so good. But the expander/topcap is totally different on cannondale.
So the question is what expander should i get? Bolt on topcap is M6. Its carbon fork and frame

No matter as long as it's an ordinary for 1 1/8 steerer. I changed my Specialized one for a Cannondale to make it lighter and because I like the Cannondale lightweight one better

THis has worked really well for me.
