Sunrace components – Derailleurs and cassettes

Company Spotlight Pro Reviews

 

Design and Construction: Cassettes

I received cogsets in TiNitride CSMZ7T and TiAlum Nitride CSMZ7. Here are some design notes:

 

  • Both cassettes were the 32t version.
  • Both are higher-end versions with the TiNitride version having gold anodized bling to remind you which is which. Apparently the Ti-Nitride coating prolongs life (the lower end versions are just plain old aluminium) but since I’ve only ridden it 30 or so days there is no perceptible long-term wear in either cassette.
  • There’s no weight difference between either cassette.
  • They are both 9 speed chain compatible

Testing Environment and Setup

The Sunrace components were used on two bikes and ridden on a variety of trails in Whistler, Squamish, North Vancouver and then in Utah (namely the St George area in South West Utah as recounted in this story. I used the components on a Specialized Demo 7 and also on a Rocky Mountain Element.

 


A missed shift on this move on St George rock ledges might result in some angst
