FAQ:

Q: How good is the Shimano 8-speed cassette?

A: The shifting is good, the chain runs well over all the cogs without skipping, it’s just what it should be if you need a replacement 8-speed cassette. I also like the gearing range; 11-32. That goes well with my hybrid bike that has a 28/38/48 chainset in front.

Q: What cassettes have 8 sprockets?

A: Shimano “Nexave” cassettes and a couple of IRD cassettes have 8 sprockets, in the narrower 9-speed spacing. A spoke-protector disk takes the place of the innermost sprocket.

Q: Is the Shimano hg51 8-speed cassette good for hill climbing?

A: With the Shimano HG51 8-Speed Cassette, you have a beefier (or lower) second gear for hill climbing. Here’s the comparison… When I say “better gearing for hills”, this is what I’m trying to convey…

Q: Are SunRace 8-speed cassettes interchangeable?

A: SunRace 8-speed combinations: When these cassettes skip the same sprocket sizes, it is fair to assume that the sprockets are interchangeable while maintaining smooth shifting. SunRace also makes 8-speed cassettes with 9-speed spacing and a spoke protector in place of the innermost sprocket, like Shimano Nexave.
