I have had several BBs with XD15 bearings on my own bikes and they have been absolutely bombproof. I have also recommended them to several riding buddies and they have reported no issues over several years. There is one friend in particular who rides at least 10,000 miles a year, and every time I service his bike, I am still shocked at how smooth the bearings are. The BB bearings on his bike must have at least 30,000 miles of use on them by now.
