Redline sealed bearings

[Waxintaxin]

Anyone know what size the spindles use that fit the 401s. i mean the newer spindles not the old dimple spindles. I am looking for the bearings i think they are proline spindles but am not 100% sure

The twin pinch 401s ones are 19mm, but I think the proline ones may be 20mm but never had any
