Last time I checked the PGM used a C-bearing… _checking_ Yes it does. A large KonKave should fit. Size C.

However, it may be hard to install the KK, as the spacers are fit on the bearing pretty tight.

If you’re refering to the second run, that’s not true.

It was one of their fixes when making it.
