Frequently Asked Questions (FAQs)
1. Can you put any freehub on any hub?
In general, you cannot interchange freehub bodies between different manufacturers. There may be some exceptions where certain hub manufacturers use compatible mechanisms, such as DT Swiss. However, it is best to stick with the original freehub that matches your specific hub to ensure proper compatibility.
2. What are the three types of bike hubs?
There are actually four types of bike hubs available: track hubs, flip flop hubs, freewheel hubs, and cassette hubs. For a fixed gear setup, it is recommended to use a track hub. These hubs have stepped threads as a distinctive feature. Depending on your specific needs and preferences, you can choose the appropriate hub type for your bike.
3. What is the difference between a freewheel and a freehub?
One significant difference between a freewheel and a freehub is the number of gears they accommodate. Freewheels typically have seven gears or less, while freehubs can have seven or more gears. Another difference is their coasting mechanism. Freewheels allow the rider to coast without pedaling, while freehubs require continuous pedaling.
4. How do I find the right freehub?
To find the right freehub, consider the number of gears on your bike. If you have 10 gears, select a Shimano/SRAM freehub. For 12 gears, choose an XDR freehub. If your bike has 11 gears, check the crank. If you have one chainring up front, go for an XDR freehub. If you have two or three chainrings, opt for a Shimano/SRAM freehub.
5. Can I swap freehubs?
No, you cannot interchange freehub bodies from different brands or models. Each brand and model of hub uses its own specific freehub body to hub interface. If you need to replace your freehub body, you should get the same brand and model as the original one on your hub to ensure compatibility.
6. What is the difference between a freewheel and cassette hub?
Cassettes are commonly used on off-road or mountain bikes due to their durability under stress and rough terrain. On the other hand, freewheel hubs are typically used for road or urban bikes where the terrain is smoother and less demanding.
7. What is the difference between a fixie hub and a freewheel hub?
The main difference between a fixie hub and a freewheel hub lies in how they operate. With a fixed wheel or fixie hub, your feet must always be moving with the pedals, even when coasting. On the other hand, a freewheel hub allows your feet to remain stationary while the bike is in motion.
8. What is the benefit of a freehub?
The freehub is a crucial component of most bikes that often goes unnoticed. It transmits your pedaling power to the road or trail, allowing your legs to rest while you are still moving. This mechanism is essential for efficient cycling and provides a smoother riding experience.
