Cane Creek ZS-3. I'm pretty sure I got it right, but it def didn't match the parts list/instructions.
Instructions say install crown race, then lower seal, then cart bearing. Well the headset only came with an upper seal and it looks like the crown race has the seal built in? So I'm assuming crown race then cart bearing (no seal required)?
Second issue is I have 3 leftover shims that the instructions fail to mention what I'm supposed to do with. I think they're extra parts for an IS install, but want to make sure I wasn't supposed to stick them somewhere?
So my install went crown race -> cart bearing -> lower cup -> upper cup -> cart bearing -> comp ring -> upper seal -> tube cap... obviously start nut and screw too.
Other than that I gotta say I saw no reason to take it to a shop. This was my first time doing it and it took me about 1.5hrs including beer drinking. Only pita was getting the head tube length right (I was afraid of cutting it too short so I errored on too long twice.
