Hubs + Freewheels

Hubs and freewheels are fundamental components of a bicycle's drivetrain, directly influencing how power is transferred from your pedals to the rear wheel. The hub, located at the center of your wheel, houses the bearings that allow the wheel to spin freely, while the freewheel or freehub body allows the rear wheel to continue rotating when you stop pedaling. This mechanism is crucial for coasting and preventing the pedals from spinning backward. Whether you're building a new wheelset, replacing a worn component, or upgrading for improved performance, selecting the right hub and freewheel ensures smooth operation, reliable power transfer, and an enjoyable riding experience across various cycling disciplines.

When selecting hubs and freewheels, several properties are important to consider for compatibility and performance. The "Installation width," often around 142 millimeters for many modern mountain bikes and road bikes, dictates whether the hub will fit your bicycle frame. Other critical factors include the number of spoke holes, which must match your rim, and the type of axle (quick release or thru-axle). The freewheel or freehub body must also be compatible with your cassette's brand and speed count (e.g., Shimano 11-speed, SRAM XD/XDR). Carefully reviewing these specifications will guide you to the correct components for your specific bicycle and riding style.
