Bike hubs: materials, types, how to choose and maintenance

What are bike hubs?

Bike hubs are the central components of bicycle wheels that house the axle and bearings, allowing the wheel to spin freely and smoothly while connected to the frame. Historically, bike hubs have evolved from simple wooden designs in the early bicycles of the 19th century to advanced, precision-engineered components made from aluminum, steel, and carbon fiber by leading manufacturers in countries like China and USA, featuring key innovations such as quick-release mechanisms and sealed bearings for enhanced performance and durability.

How hubs work on a bike?

Hubs work on a bike by serving as the central pivot point around which the wheel rotates. The hub contains an axle, bearings, and a shell that connects to the spokes of the wheel. The axle is fixed to the bike frame, and the bearings allow the hub shell and wheel to rotate around the axle with minimal friction. The structure of the hub affects performance by influencing rolling resistance, durability, and weight distribution.

1. Axle: The axle is secured to the frame via dropouts. It supports the rider’s weight and the forces exerted during riding. Axles can be solid or hollow (quick-release and thru-axle designs), affecting weight and ease of wheel removal.
2. Bearings: Bearings inside the hub reduce friction and allow smooth rotation. There are two main types: loose ball bearings and cartridge bearings. Cartridge bearings are sealed, providing better protection against dirt and moisture, leading to lower maintenance and longer lifespan.
3. Hub Shell: The hub shell houses the bearings and attaches to the wheel’s spokes. It must be strong enough to withstand the forces transmitted through the spokes while being lightweight. Materials like aluminum and carbon fiber are commonly used to balance strength and weight.
4. Flanges: The hub shell features flanges where spokes are attached. The flange design and spoke lacing pattern (radial, 2-cross, 3-cross, etc.) impact the wheel’s stiffness and load distribution.
5. Freehub Mechanism (Rear Hubs): The rear hub includes a freehub mechanism that allows the bike to coast without pedaling. It contains a ratcheting system that engages the wheel when pedaling and disengages when coasting, providing efficient power transfer.

The interaction of these components determines the hub’s performance. High-quality bearings reduce rolling resistance, improving efficiency. The material and design of the hub shell and flanges affect the wheel’s strength-to-weight ratio and durability. The freehub mechanism in rear hubs ensures smooth and efficient power transfer while allowing coasting, crucial for dynamic riding.

What is pawls in bike hubs?

Pawls in bike hubs are small, spring-loaded levers that engage with the ratchet mechanism inside the freehub body, allowing the hub to transfer pedaling force to the wheel when engaged and to freewheel or coast when disengaged, ensuring efficient power transfer and smooth riding.

Are hubs all the same dimensions on bike?

No, hubs are not all the same dimensions on bikes because different types of bikes and riding styles require varying hub widths, axle standards, and flange distances to accommodate different frame designs, wheel sizes, and performance requirements.
