Sunrace Compatibility
Posted on 12th, January 2021 about V3 BOOST Rear Hub - 32 Hole by G. Rossari

unfortunately I discovered that the V3 hub with XD is not compatible with the Cassetta 12V SUNRACE CSMZ91X, due to the diameter of the axle of too large diameter, this causes problems also with the original Sram GX cassette, making it difficult to tighten and unlock the cassette, for the rest I would say a fantastic, long-lasting, light and smooth hub. Sorry for my English!
Superstar comment - it is compatible you just need the correct thin wall lockring tool. normal lockring tools dont fit as you say but this is the same with all modern hubs.
