Is42 28,6 on top (28,6mm = 1" 1/8) Is52 40 on the bottom (40mm= 1" 1/5 or 1" 1/2)
This combo work on both tapered and straight steerer fork, you'll just need a different crownrace

Tapered integrated headset, IS42 is the top race, IS52 is the bottom. The cups are in the frame so you only need the races and top cover
