I don't think Lifeline carbon one will work . The frame needs an IS42 headset (bearing od=41.8mm) . That headset says it is IS41 (bearing od 41.2). A small difference I know but I think IS42 is the propriety Campag format that caad 5/6/7 frames use .
The non carbon lifeline version is actually listed as IS42 for some strange reason. I was wary of these lifeline ones for my Caad7 so ended up going for a Cane Creek 40, which is a really nice piece of kit, worth paying the extra for imo. Or the slightly cheaper FSA as mentioned above
Buy lifeline carbon headset + have new frame made to fit !
Seriously though maybe just check with wiggle they've probably listed one of them incorrectly, or buy both lifeline headsets to check and/or mix and match then send the leftover parts back!
