Wheels MFG.
I used a thread together BB86 for my Shimano crankset, then switched to their PF when I switched to a DUB crankset. Yeah, I'm enjoying the comparatively mild So Cal weather and mostly glass smooth roads, but I did take the bike back East for a couple of weeks. Rode a couple hundred miles through some torrential downpours, mud, grit, terrible roads, but the PF held up nicely. Still going with the original bearings.
