I have a friend interested by he Rise & Müller Birdy and one question about the Birdy Touring with the Sunrace hub (which is the only remaining R&M Birdy with rear derailleur): is it possible to mount a standard Shimano/SRAM cassette on this hub ?
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 ?
