Had purchased new wheels for my son's mtn bike with Shimano hubs. Noticed when repacking the bearings, the front hub did not have much grease at all, barely even slick. Plus that hub was overly tightened by the manufacturer.
Rear hub did have some grease, but not that much.
Wondering if the production on these hubs are going too fast or quality control is just plainly down for these kind of mistakes.
