How can you tell the group (ultegra, 105, etc.) of an older hyperglide cassette?
I'm trying to purchase a replacement 8-speed shimano HG cassette for a
bike on ebay but it seems like most people don't know what group the cassette they're selling is from. Is there any easy way to tell? Are they all the same material? Thanks. Jordan |

Jordan They're all interchangeable, but the lower "grades" would have brown-colored cogs while the upper grades would have silver cogs. On mountain groups, better cassettes will have the larger cogs on an aluminum carrier, with the best having a couple titanium cogs. Jeff |

Jordan Shimano has fewer quality levels of cassette than they do groups, and most levels of cassette can be seen in some places branded as "going along" with multiple groups at different-but-close-ish quality levels, but it's not made obvious in these cases. So for example HG-50 cassettes have been associated with Tiagra, Deore, I think RX100, etc. The higher end groups (DA, XTR, 6800 Ultegra, etc) usually but not always get a model number to themselves. If you look through Shimano's pages you should be able to get the info you need, and sellers should always be able to find the HG-whatever model name. There's a number of things that differ between cassettes of different price levels but it mostly involves weight (materials, cutouts, whether the cogs are spidered or not, etc). Durability varies as well, but not very much in my experience. All but quite high end cassette cogs are steel. Some high end cassettes have some Ti cogs, and some others have some aluminum, and some race-day-ish cassettes are full aluminum. Shimano-compatible SRAM cassettes are generally priced to edge out Shimano's own cassettes at similar quality/weight levels, and are favored by many. |
