Roval AFD2 Rear hub dimensions

[BespokeCPT]

Hi all,

I need to take on a rebuild, where a 24H C38 carbon rim will be built over onto the above rim, a Roval AFD2 24H SP rear hub. These are normally fitted with the CL32 Rapide 24H carbon rim and laced to a J-bend DT Swiss 350 hub (swopping rim from a front wheel, to be built onto rear wheel with mentioned Roval AFD2 hub), and due to ERD difference of around 10mm, will require new spokes for the lace up. To further compind the rebuild, laceup will be 2:1 Triplet with straight pull spokes. So not spoke calculator friendly.

Does anyone have the hub dimensions that can with worked with, or a technique that can be used to work out the required spoke lengths?

Cheers
