130mm rear hub

Types of 130mm rear hub

A 130mm rear hub is a part of a bicycle wheel that connects the wheel to the bike frame. It is located in the center of the wheel and contains the axle on which the wheel spins. The 130mm measurement refers to the distance between the two dropouts on a bike frame where the hub is installed. Here are some types of 130mm rear hubs:

• Freehub body: The freehub body is a part of the 130mm rear hub that holds the cassette, which contains the gears used for shifting. It allows the rider to change gears by moving the chain onto different-sized cogs. The freehub body is compatible with various cassette configurations, such as 8-speed, 9-speed, or 10-speed systems. However, 8-speed cassettes are less common, so they are mostly used on vintage bikes. The difference in compatibility comes from the design of the freehub body, which is slightly different for each speed system. When choosing a replacement freehub body, it's important to select one that matches the number of speeds on the existing cassette.
• Type of disc brake rotors: 130mm rear hubs are compatible with different types of disc brake rotors. This includes 6-bolt and Center Lock systems. The 6-bolt rotor uses six bolts to attach to the hub, while the Center Lock rotor slides onto a splined interface and is secured with a single locking nut. Some 130mm rear hubs are designed for quick release axles, while others accommodate thru-axles for added strength and stability.
• Hub shell material: 130mm rear hubs are made from various materials, including aluminum, carbon fiber, and steel. Aluminum is the most common material for hub shells because it is lightweight and resistant to corrosion. Carbon fiber shells offer superior strength but at a higher cost. Steel is the heaviest option but provides good durability under heavy use.
• Internal hub gears: Some 130mm rear hubs contain internal hub gears instead of external derailleur gears. Internal hub gears offer low maintenance and smooth gear changes, making them popular on city and commuter bikes. The gearing system on these hubs can range from 3 to 14 speeds, providing a reliable and efficient way to transfer pedal power to the wheels.

Specification & Maintenance of 130mm rear hub

• Regular Cleaning

  Use a soft brush or cloth to clean the hub and spokes regularly to remove dirt and dust. This helps keep the hub working well.

• Lubrication

  Put lubricant on the freehub body and axle as needed. This makes it spin smoothly. Use a lubricant made for bicycle hubs.

• Spoke Tension

  Check that the spokes are tight. If they are loose, use a spoke wrench to tighten them. This keeps the wheel in good shape.

• Seal Inspection

  Look at the seals around the hub. Make sure they are not cracked or worn. The seals keep water and dirt out of the hub.

• Bearing Check

  Spin the hub to feel the bearings. They should move smoothly. If the bearings feel rough, take the hub apart and put new bearings in.

• Axle Nut Security

  If the hub uses nuts on the axle, make sure the nuts are tightened. Loose nuts can cause the hub to wobble.

• Hub Body Inspection

  For cartridge and freehub body hubs, take the body off and look for cracks. Replace any parts that are damaged.

• Hub Adjustment

  If the hub is adjustable, follow the instructions to set it correctly.

How to choose 130mm rear hubs

When buying a 130mm rear hub, always consider the audience's needs. Some factors to consider are as follows.

• Bike Type

  Consider the type of bike the hubs will be used on. Different bikes have different requirements when it comes to rear hubs. For instance, most road bikes use the 130 mm rear hub as they are lighter and faster. On the other hand, mountain bikes require hubs that can handle rough trails and more suspension travel.

• Riding Style

  Different riders have different preferences and styles. It is important to consider this when choosing a rear hub. For instance, casual riders who ride for leisure do not require high-performance hubs as they are not hard on the components. Competitive cyclists, on the other hand, require high-quality hubs that offer low rolling resistance.

• Axle Configuration

  One must consider how the rear wheel is attached to the bike frame. Is it done using quick-release levers or through bolts? Different bike frames require different axle configurations. Ensure to choose a rear hub that is compatible with the bike frame.

• Material

  The rear hub is available in different materials such as aluminum and steel. Each material has its advantages and disadvantages. For instance, aluminum hubs are lightweight making them suitable for racing. Steel hubs, on the other hand, are more durable and can withstand heavy loads.

How to DIY and Replace 130mm rear hub

Most of the time, replacing the 130mm rear wheel hub can be a DIY task that every bike enthusiast can handle. Follow the simple steps below.

Tools needed:

• Hub wrench or screwdriver
• Allen keys
• Grease
• New bearings (if required)
• Replacement freehub body (if required)

Steps

• Disassembly

  Use a wrench or an Allen key to loosen the nuts or bolts securing the hub to the wheel. After that, remove the hub's cover or dust cap to access the internal components.

• Remove the Bearings

  Use a hub wrench or screwdriver to remove the bearings. Take note of their orientation and placement.

• Replace the Freehub Body (if needed)

  If the freehub is damaged beyond repair, remove it from the hub shell. This is usually done by loosening a few screws. Then, install a new freehub body and ensure it is securely fastened.

• Reassemble

  Put the bearings back into their respective positions and then replace the hub cover or dust cap. Finally, secure the hub to the wheel using the nuts or bolts.

Q and A

Q1: What is a 130mm rear hub?

A1: The 130mm rear hub refers to the distance between the two rear dropouts on a bike frame. It is a standard measurement used on many road bikes and some gravel and cyclocross bikes. The 130mm rear hub allows for quick and easy wheel installation and removal while maintaining proper wheel alignment and stability.

Q2: Why is the 130mm rear hub important for bike performance?

A2: The 130mm rear hub offers several benefits that enhance bike performance. It provides a stiffer and more stable rear wheel, which improves power transfer and acceleration. This is especially important for competitive riders or those who strive for efficiency in their cycling performance. Additionally, the 130mm rear hub allows for precise wheel alignment, reducing friction in the rear wheel and prolonging the life of the hub and the entire drivetrain system.

Q3: Can the 130mm rear hub be used on bikes other than road bikes?

A3: While the 130mm rear hub is primarily associated with road bikes, it is also used on some gravel and cyclocross bikes. These bikes are designed for off-road and mixed-terrain use, requiring the 130mm rear hub's strength and performance benefits. The 130mm rear hub can also accommodate disc brakes and wider tires, making it suitable for gravel and cyclocross bikes.
