Frequently Asked Questions (FAQs)
1. Are all 9 speed Shimano cassettes compatible?
Yes, Shimano 8, 9, and 10-speed cassettes are fully interchangeable for wheels with steel Freehub bodies. The main difference between these systems lies in the shift control levers.
2. Is there a 9 speed freewheel?
Yes, the SunRace MFE909 9-Speed Freewheel is available for bikes with a 9-speed drivetrain.
3. Are all 9 speed cassettes the same?
For 9-speed cassettes, they generally have the same width of sprocket teeth and are compatible with 7/8 or 9-speed chains. However, older Uniglide 6-speed cassettes have larger spacing between sprockets and may have shifting issues.
4. Which is better freewheel or cassette?
A cassette is generally considered better than a freewheel. While changing a cassette requires more tools, a freewheel that has been on a bike for a while can be difficult to remove. Cassettes are more suitable for riding on various terrains and at different speeds.
5. Can I put a 10-speed cassette on a 9 speed hub?
Yes, you can put a new 10 or 11-speed cassette on an older 9-speed hub, regardless of the brand. Upgrading to a higher-speed cassette is possible and compatible with the 9-speed hub.
6. What is the difference between a freewheel cassette and a freehub?
Cassettes are typically used on off-road or mountain bikes due to their durability under stress and bumps. Freewheel hubs, on the other hand, are commonly used on road or urban bikes, where rough and shocking terrain is less of a concern.
7. Can I upgrade a 9 speed cassette?
Yes, you can upgrade a 9-speed cassette. Regardless of the brand, you can put a new 10 or 11-speed cassette on any older 9-speed hub, allowing you to enjoy the benefits of an upgraded cassette on your bike.
8. How many miles should a bike cassette last?
The lifespan of a bike cassette can vary depending on factors such as chain wear. If you change your chain every 1500 miles, you can expect a cassette to last around three chains, which is approximately 4500 miles. However, if you don't change your chain regularly, you may only get around 3000 miles out of a cassette.
9. How do I know what cassette to get for my bike?
The cassette speed is determined by the number of sprockets on it. Your bike may have a cassette with anywhere from 7 to 13 speeds. Lower-priced cassettes usually have fewer sprockets, while higher-end cassettes, especially for road and mountain bikes, tend to have 12 speeds as the default option.
