I'm going to be replacing the cartridge bearings in my IRO hubs with Phil Woods. Not sure what size or model I need, I'm thinking the 6001?

I think you need 6000 series. If you take the locknuts off you can see a tiny numbering on the seal of the bearing, it's either 6000 or 6001. You need to make sure and order the right series.

Scroll through and you'll get all the links you need. Let us (or me) know how it pans out. I've been wanting to swap but keep blowing my money on pointless crap.
