Duke runner 30 rims

[Shmitt]

I have a rather unusual question, but it is important when it comes to completing the equipment.
How long are Presta valves needed for this type of rim? 48 [mm] or 60 [mm]?

[MasterBean]

The formula is usually rim depth plus 13 which makes 43 so probably 60mm valve but you might just get away with a 42 as it is close.
