I have 3 bikes with 2 wheelsets each for a total of 6 different rear wheels that I need to keep track of. All of the cassettes that I run are Sunrace except for 1 which is Shimano. The hubs are either Shimano/SRAM 10 speed or 11 speed freehub bodies. Here's the breakdown of what I'm running:
- 10 speed - 11-42 Sunrace (10 speed hub - No Spacer) & Shimano (11 speed hub - 1.85mm spacer)
- 11 speed - 11-46 Sunrace (11 speed hub - 1.85mm spacer)
- 12 speed - 11-50 Sunrace (10 speed hub - No Spacer) (11 speed hub - 1.85mm spacer)
I noticed mainly when switching wheelsets that I might not have proper cassette spacing, so I looked around around this image:
Looking at this, it seems like I need to add a 1mm spacer to the 10 speed Shimano cassette, but what about the rest? I'm not sure if Sunrace cassettes are spaced similar to either Shimano or SRAM. What's also complicated was that the 11 and 12 speed mountain cassettes are supposed to be spaced similar to 10 speed cassettes, so I'm under the impression that I still need the larger spacer. I guess I just need to know if I need to add the 1mm spacer to my Sunrace cassettes.
