Difference Between Bicycle Freewheel And Cassette
Introduction
When it comes to cycling, there are many components that make up a bicycle. Two of these components are the freewheel and cassette. Both of these components are responsible for allowing the bike to coast without pedaling. However, there are some key differences between the two that you should be aware of before making a purchase.
Bicycle Freewheel
A bicycle freewheel is a component that allows the rear wheel to turn freely in one direction while still being able to apply power in the opposite direction. This is important because it allows you to coast without pedaling, which is useful when going downhill or taking a break from pedaling. The freewheel is typically threaded onto the hub of the rear wheel and can be easily removed and replaced.
Cassette
A cassette, on the other hand, is a component that includes a set of sprockets that are mounted onto the rear wheel hub. The cassette is typically held in place by a lockring and can be easily removed and replaced. Similar to the freewheel, the cassette allows the rider to coast without pedaling. However, the cassette is typically found on higher-end bikes and provides a wider range of gear ratios compared to a freewheel.
Differences
One of the main differences between a freewheel and cassette is the number of gears. Freewheels typically have fewer gears, while cassettes can have up to 12 or more. This means that cassettes are typically found on higher-end bikes that require a wider range of gear ratios. Additionally, cassettes are typically easier to remove and replace compared to freewheels.
Another difference between the two is the way they are attached to the bike. Freewheels are typically threaded onto the hub of the rear wheel, while cassettes are mounted onto the hub using a spline interface. This makes cassettes more secure and less likely to come loose while riding.
Finally, cassettes tend to be more expensive compared to freewheels. This is due to the fact that cassettes typically have more gears and require a more precise manufacturing process. Freewheels, on the other hand, are simpler in design and can be manufactured at a lower cost.
Conclusion
When it comes to choosing between a freewheel and cassette, it ultimately comes down to personal preference and the type of riding you will be doing. If you are a casual rider and don't require a wide range of gears, a freewheel may be the better option for you. However, if you are a serious cyclist or plan on doing a lot of climbing, a cassette may be the better option due to its wider range of gear ratios.
