Sunrace CSMZ91 12 Speed Cassette 10-50t For SunRace Cassette Body
Note: SunRace Cassette Body Compatible ONLY – Not Compatible With SRAM Or Shimano Cassette Bodies
SunRace Cassette Body ONLY Compatible With Rapidé Hubs
The SunRace CSMZ91 WT5 10-50t 12 Speed Cassette delivers the advantages of a 10 tooth top gear in a surprisingly logical way.
A small step-down is designed into the end of an otherwise standard cassette body and this allows the smaller 10t cog to fit. The cassette is constructed in the same way as the other lightweight cassettes in SunRace’s range – two lightweight alloy carriers with cogs attached.
The 10t and 12t cogs are machined out of a single piece of high tensile steel.
Because the cassette and cassette body are based on existing designs the manufacturing cost is lower.
Standard Cassette Body
SunRace Cassette Body
Built with light weight alloy cog carriers, hard wearing chromoly 10-36t cassette cogs and AL7075-T6 42t and 50t cogs to keep the weight down and drivetrain stiffness up.
The inclusion of a 10t cog gives you a taller top gear for flat terrain and down hills while leaving the climbing gear ratios unaltered.

7 cogs on 2 aluminium spiders
Black Chrome finish
Optimized gear ratios
