Needing to change the headset on my c456

Can someone tell me the correct hope top & bottom cup I need on the pick & mix headset?

Many thanks…

Ps using 1 1/8 steerer

Yep. Top is a “2” bottom is a “D” I used the low stack option. Iirc ofcourse.

Edit:

Yep crc call it a stepdown 49.57 low.

Check jejames though as I got mine cheaper there than crc. Also bike outlet and bike store if you want too try price matching.

Offered an as new one, top is no 2 ok

Bottom is integrated e, no good then?

needs to be an external cup lower one.

So no 2 top
D bottom deffo?
