I would advise against the Cane Creek one anyway. Got my Five in June with the CC headset, in November it was unused for 3 weeks due to illness (me not the bike, before anyone asks) and during that time the headset seized. When I stripped it down the lower (cartridge) bearing was really rough but the upper (caged) bearing was almost solid. What grease was left was filthy and gritty. Seems poorly sealed with low rate bearings to me.
I had a Hope headset on my previous bike which was much better sealed and ran smoothly for 7 years (until bike was nicked) with minimal maintainance.
Go for the Hope, give them a call and they’ll keep you right as to which one you need.
