When it comes to bikes, there are numerous components that work together to give you a smooth and efficient ride. One of these components is the hub, which is responsible for connecting the wheels to the frame and allowing them to rotate smoothly. However, not all hubs are created equal. Some have a boost design, while others do not. So what exactly is the difference between boost and non-boost hubs? Let’s explore in detail.
Firstly, let’s define what boost hubs are. Boost refers to the spacing of the axle on the hub. Boost hubs have a wider axle spacing of 110mm for the front hub and 148mm for the rear hub. In comparison, non-boost hubs have a narrower axle spacing of 100mm for the front hub and 135mm for the rear hub. This extra width on the boost hubs allows for wider hub flanges and a wider spoke bracing angle, resulting in a stiffer and stronger wheel.
One of the main advantages of boost hubs is that they increase the overall stiffness of the wheel. This is especially beneficial for riders who are tackling rough and technical terrain as it allows for better handling and control of the bike. The wider hub flanges also provide a stronger foundation for the spokes, reducing the likelihood of them flexing or breaking. This results in a more durable wheel that can withstand the demands of aggressive riding.
Another significant difference between boost and non-boost hubs is the increased clearance they offer. With a wider axle spacing, boost hubs make it possible to run wider tires on your bike. This is especially useful for riders who prefer a more aggressive tread pattern for better traction and control. Additionally, the increased clearance also helps to prevent mud and debris from building up between the tire and the frame, reducing the risk of wheel lockup or damage to the frame.
One of the biggest advantages of non-boost hubs is their compatibility with older bike frames. Many bikes manufactured before the introduction of boost hubs have narrower axle spacing, making them incompatible with boost hubs. Upgrading to a boost hub would mean having to also replace the bike frame or fork, which can be a costly and time-consuming process. On the other hand, non-boost hubs can easily be installed on both old and new frame designs, making them a more versatile option.
Weight can also be a significant factor when it comes to boost vs. non-boost hubs. Boost hubs are slightly heavier than non-boost hubs due to the wider hub flanges and increased material, but the difference is minimal. This additional weight is hardly noticeable, and for many riders, the performance benefits of boost hubs outweigh the slightly heavier weight.
Another key difference between boost and non-boost hubs is the availability of replacement parts. As boost hubs are a relatively new addition to the market, finding replacement parts can be more challenging compared to non-boost hubs, which have been around for a longer time. However, this may not be a major issue for most riders as the chances of needing to replace major parts, such as the hub shell or axle, are quite slim.
In terms of pricing, there isn’t a significant difference between boost and non-boost hubs. However, as boost hubs are relatively new, they may be slightly more expensive compared to non-boost hubs. As with most bike components, prices can vary depending on the brand and materials used, so it’s essential to do your research and choose the best option within your budget.
In conclusion, the main differences between boost and non-boost hubs are the axle spacing, stiffness, clearance, compatibility, weight, availability of replacement parts, and pricing. Boost hubs offer increased stiffness and clearance, making them ideal for aggressive riding, but they may not be compatible with older bike frames. Non-boost hubs, on the other hand, offer versatility and easy compatibility, making them a more practical option for most riders. Ultimately, the choice between boost and non-boost hubs will depend on your riding style, terrain, and personal preference.
