On the Sabliere I think the "cups" are really bearing shields, close fitting to exclude dust and water
The bearings themselves need to be pressed out. I use an arbor press for this job.
The bearings sit in the shell but further in than with Klein, Fisher/Ritchey, and Ritchey (and probably hundreds of other over the years) which have the bearing either flush with the side of the shell or they use a bearing with a lockring groove and just seat the lockring up against the side of the shell. I have bought lots of Phil plain spindles for this purpose.Typically the spindle is positioned in the shell by lock rings although I've seen a lot of other clamping methods over the years.
We need pictures of this Sabliere.
