Jon T, that is interesting on your well used PH10LE. One thought that occurred to me was the small bearings weren’t up to the weight they needed to carry. You frame is larger, indicating you are larger, so that theory bites the dust. Hobbiano references his proper upkeep and failures too.
What’s left? Quality of factory bearings and cones? Quality replacement bearings? Magic dust, or karma? It is encouraging to see one positive report of good luck with this hub. Funny that the steel bits would go as compared to the softer and seemingly more fragile aluminum body.
