Apologies if already covered elsewhere - have done a bit of searching, but didn't find the info I was after.

Headset on my Supersix Evo is sounding pretty rough. Planning to disassemble, clean and grease tomorrow - which will hopefully sort it - but wondered if anyone had picked up replacement cartridges for an Evo and knew off-hand which ones I'd need?

Not after the whole headset assembly, just the upper (specs say, 1 1/8" Campag hidden) and lower (1 1/4" Cannondale). Have had a stab at searching the Simply Bearings site, but it's pretty confusing...
