Wheel bolt for axle diameter 9 mm

Everything you need to know about bicycle bolts: a small component with big consequences

The bicycle bolt is an essential component of the wheel attachment system. Often overlooked, it ensures the stability and safety of the cyclist by providing optimal wheel retention on the frame or fork.

The different types of bicycle bolts

There are several types of bicycle bolts, each with specific characteristics depending on the attachment system and bike type:

• Standard threaded bolt: ideal for classic wheel axles, offering a robust fixation.
• Quick-release bolt: common on road bikes and modern MTBs, allowing instant wheel removal.
• Anti-theft bolt: designed to prevent theft, requiring a special tool for loosening.
• Hexagonal or torx head bolt: provides better force distribution and optimal tightening torque.

Materials and dimensions of bicycle bolts

The choice of material affects the durability and weight of the bolt:

• Stainless steel: corrosion-resistant and strong.
• Titanium: extremely lightweight and durable but expensive.
• Aluminum: lightweight and aesthetic but less durable than steel.

Bolt dimensions vary depending on the axle type and bike standard. The most common diameters are M5, M6, and M9, with lengths adapted to specific needs.

How to choose and maintain your bicycle bolt ?

To ensure optimal wheel attachment, it's crucial to choose a bolt compatible with your bike. Make sure to:

• Verify that the threading matches your hub.
• Opt for a resistant material according to your needs.
• Regularly check the condition and tightness of the bolts to avoid any looseness.

In case of wear or corrosion, replacing bolts is recommended for optimal safety. Proper maintenance includes applying anti-seize grease and tightening to the recommended torque.

Conclusion

The bicycle bolt, though small, plays a crucial role in the reliability and performance of your bike. Whether for daily commuting, sports, or urban cycling, selecting and maintaining suitable bolts ensures a safe and smooth riding experience.
