Which Extralite Ultratop for 2018 Evo Hi Mod?

[dereksmalls]

Sorry to bother everyone, I don’t have the time or tools to remove my headset and measure it to figure out which Extralite ultratop I’d need for a 2018 Cannondale Evo Hi Mod, so was wondering if anyone could help me out in sussing the right one?

The Cane Creek AER is light but isn’t holding up I have to say. I’ve been through 2 bushings already
