So.. Just to clear things up, which Phil spec'd bearing is an exact match for the bearings in the Nashbar track hubs?

I see that the Nashbar hub is a 6000 series, but Phil has several bearings that begin with 6xxx, but nothing that says '6000' specifically.

Anyone know for sure? Otherwise I'll disassemble one and measure with my .001" micrometers, but I just dialed in my chain tension, and I don't want to lose it if I don't have to.

peace,
sam
