Can you tell if i have ZS or IS headtube from these pictures? I feel a smooth ridge on both ends of the tube right after the cup. Do i need to take off the cups to get a decent measure? I dont have any special tools and theres a set of caincreek 40zs44 that i can buy. Is 44 tube standardized?

They look to be pressed in ZS cups
Agree with the other poster that you’ve got pressed in ZS cups.
I think you’ve got a tapered headtube, and annoyingly there are two very very close sizes for the lower headtube in this size – ZS55/40 and ZS56/40. You need to drift out the cup and measure, or ask the manufacturer. The upper is probably ZS44/28.6
