The world of biking technology is ever-changing, and riders must stay on top of the latest advancements to ensure that their bikes perform optimally. One way in which riders can ensure the proper performance of a bike is to understand the current Hub spacing standards for both 20 and 24-Inch Wheels. Being knowledgeable about hub spacing and how to properly install the hub are both essential components for any bike enthusiast.
What Is hub spacing?
hub spacing is the distance between two hubs on a bicycle wheel, measured in millimeters. In simple terms, hub spacing is the sizing of the frame to accommodate a specific wheel size. For example, a bike designed specifically for a 20-inch wheel will have a much larger hub spacing than one designed for a 24-inch wheel. As components on the bike change, the hub spacing may change to accommodate those components or the wheel size.
For 20-inch wheels, there are three common standards of hub spacing. The most common hub spacing for a 20-inch wheel is 135 millimeters. The 135mm hub spacing is often used on mountain bikes and BMX bikes, as it provides a larger hub spacing than is readily available for smaller wheels. The next popular hub spacing for a 20-inch wheel is 120 millimeters. This is often used on cruiser bikes and beach cruisers. The last common hub spacing for a 20-inch wheel is 100 millimeters and is used primarily for road bikes or touring bikes.
24-inch wheels
For 24-inch wheels, the most common hub spacing is 130 millimeters. This is often used on mountain bikes and BMX bikes as it offers a bit more stability. The next common hub spacing for a 24-inch wheel is 126 millimeters. This is often used on cruiser bikes and beach cruisers. The last common hub spacing for a 24-inch wheel is 100 millimeters and is used primarily for road bikes or touring bikes.
Understanding hub spacing standards
It is important for riders to understand the current hub spacing standards so that their bicycles can accommodate the size of wheel that they wish to use. Insuring that the wheel is properly seated in the hub is essential, as the incorrect size of wheel can cause the bike to experience excessive torque, wear, and tearing. Understanding the current hub spacing standards also make it easier for riders to know when components need to be replaced, as components with a different hub spacing will not be compatible with a bicycle frame designed for a different hub spacing.
Once the rider is familiar with the hub spacing and the wheel that needs to be installed, the actual installation process can begin. It is essential for the installation to be done correctly in order to avoid any damage to the frame or wheel. The hub should always be bolted on to the wheel first, then attached to the frame in the designated slot. Tension should be checked at multiple points to ensure that the wheel is secured properly. It is highly recommended to have a professional install any new wheels or components.
Conclusion
understanding hub spacing standards is essential for any avid bicycle rider. It is important to understand the size of wheel that is needed, and the size of hub spacing needed to accommodate it. Failure to properly adjust the hub spacing can cause damage to the bike. Having a professional assist with the installation of new hub or wheel components is the safest and most reliable way to get the most out of any bicycle.
