Or does it accept only the proprietary Sunrace cassette ?
There is very little information available on the web about this hub !
Nothing is said on the Sunrace website about the compatibility of their only hub (HBSX1 for disc brake, HBSX0 for rim brakes) and their 4 types of cassettes (CSSS) 10s and CSSX0 11s), seem the same hub accept 10s and 11s cassettes ?
The sunrace hub which accepts 9t cassettes fits only these special sunrace cassettes. Both 10 and 11 speed fit, I have used both. (The old shimano capreo cassettes MAY fit, there is some indication the hub is a clone of those, but they are obsolete anyway.) It will NOT fit standard shimano/sram cassettes. It will also NOT fit sram xd cassettes.
It is also a weak hub in my experience, I can not recommend it for strong and/or heavy riders.
