Hullo, just like to inquire. Before doing the testing, did you service the original bearings? Clean them totally clean, removing the original lube? Then doing the test with with the original and boca bearings with the same lube?
I’ve done some tests like this and found there is no difference in distance once you do this. The best way to get the best performance out of the bearings is to clean them up and use low viscosity bearing oil. It’s not so much the bearing “quality”. The new bearings from boca are delivered dry, so they will perform better than the original bearing which are normally lubed with heavy oil.
