I'm noticing the big alloy cog on my ZTTO 9-46t isn't very durable. Even from light use, the teeth appear to wear quickly. It defeats the purpose of using such a cassette since climbing is the reason to have such low gearing. In comparison, I'm also using a Sunrace 10-46t and the alloy big cogs are far more durable. The teeth are thicker as well.
Are there any other cassettes worth checking out within a reasonable price range? Thanks!
