Measured and pair shells obviously still very elegant and clearly tightening the clearance spec, but we're no talking night and day and the "risk" of getting the maximun 0.016mm clearance difference must be negligible.
The BE folks quote a wider production tolerance of I believe 0.013mm (due to the coating) hence increased reason to go through the process.
to tell the truth, it is very difficult for me to understand))
BE provides bearings with such a tolerance and then the dealer pairs them (up and down)?
** the "risk" is that you can get the wrong tolerance if the dealer did his job irresponsibly??
am I right?
