Conversion kits & freehubs

Conversion kits and freewheels for bicycle hubs are essential components that allow bicycles to be adapted to different needs and drive types. These products are particularly widespread in the area of mountain bikes, road bikes, and gravel bikes, as they offer flexibility and individual customization options.

A conversion kit allows certain parts of the hub, such as the axle or bearings, to be adapted to a new bike or different standards. A common example is converting from quick-release skewers to thru-axles, which provide a more stable connection between the frame and the wheel. Thru-axles are preferred in many modern bikes as they offer greater stiffness and precision. Conversion kits often include the appropriate adapters and axles, allowing riders to use older wheels with new axle standards. This is especially useful for updating a bike with the latest technologies without having to purchase a completely new wheel.

The freewheel is another important part of the bicycle hub, allowing the rider to coast without having to constantly pedal. Modern freewheel systems have evolved in recent years, now offering a higher number of pawls and faster power transfer. This improves efficiency when riding, particularly on technical trails where quick engagement of the drivetrain is crucial. High-quality freewheels are often made of durable materials like steel or titanium to withstand high stresses. Some manufacturers even offer specific freewheel bodies for different cassette types, allowing easy adaptation to various drivetrains.

In summary, conversion kits and freewheels offer a wide range of options to adapt the bike to personal needs and modern standards. They help extend the bike's lifespan and make it easy to optimize performance.

Notable manufacturers of freewheel bodies and conversion kits include: Campagnolo, Fulcrum, Extralite, White Industries, Ritchey, Mavic, Vision, and FSA.
