Is Quick Release 130 or 135?
Quick release, a term used in the world of bicycles, can be confusing, especially for those new to the world of cycling. The quick release is the mechanism that secures the wheels to the frame of a bicycle, allowing for easy removal and installation. However, there is a long-standing debate about the correct size of quick release for a bike. In this article, we’ll dive into the history and significance of quick release sizes, answering the question: Is quick release 130 or 135?
History of Quick Release Sizes
Quick release sizes have evolved over the years to accommodate changing bicycle designs, materials, and technologies. In the early days of cycling, frames were built with steel lugs and axles, which allowed for the use of older-style quick release mechanisms with a width of around 130mm. These early quick releases were commonly used on road bikes, while mountain bikes and other applications used slightly different sizes, such as 135mm.
Current Standard: 9x100mm and 10x135mm
Today, the most common quick release sizes are 9x100mm for front wheels and 10x135mm for rear wheels. This is due to the widespread adoption of aluminum and carbon fiber frames, which require stronger, more durable quick releases. The 9x100mm size is typically used for road bikes, while the 10x135mm size is used for mountain bikes, gravel bikes, and other applications where a stronger axle is necessary.
What is a QR Axle?
A QR axle, also known as a quick release axle, is the hollow tube that passes through the frame of a bicycle and connects the wheel to the quick release mechanism. QR axles come in different diameters and widths, which must match the quick release size to ensure proper installation.
Significance of QR Axle Width
The width of the QR axle is crucial in determining the correct quick release size for a bike. A QR axle with a 9mm diameter typically uses a 100mm wide quick release, while a 10mm diameter QR axle uses a 135mm wide quick release.
Summary of Quick Release Sizes
Here is a summary of the common quick release sizes and their corresponding QR axles:
| QR Size | QR Axle Diameter | QR Axle Width | Typical Use |
|---|---|---|---|
| 9x100mm | 9mm | 100mm | Road bikes, front wheels |
| 10x135mm | 10mm | 135mm | Mountain bikes, rear wheels, gravel bikes |
Can You Use a 130mm QR Axle with a 10x135mm Quick Release?
The short answer is no, you cannot use a 130mm QR axle with a 10x135mm quick release. The QR axle width must match the quick release size to ensure proper installation and safe riding.
Conclusion
In conclusion, the debate about whether quick release is 130 or 135 is largely a matter of history and terminology. Modern quick release sizes are 9x100mm for front wheels and 10x135mm for rear wheels, and it is essential to use the correct QR axle width to match the quick release size for safe and proper installation.
Important Notes
• Always check your bike’s manual or manufacturer’s website to confirm the correct quick release size for your bike.
• Never attempt to use a quick release size that is not specified for your bike, as this can lead to accidents or damage to your bike.
• If you are unsure about the correct quick release size for your bike, consult a professional bike mechanic for assistance.
