What is the difference between thru-axle and quick release?
3 Answers
The differences between thru-axle and quick release are as follows: 1. Different configurations: Thru-axle comes with a quick-release lever, while quick release does not include a quick-release lever, as it is sold together with the axle. 2. Different diameters: Thru-axle typically has a diameter of 15MM or 20MM, offering significantly higher strength compared to the 9MM quick release. 3. Different weights: The quick-release fork is relatively lighter, while the thru-axle is comparatively heavier. If weight is not a concern but strength is prioritized, thru-axle can be used, but attention should be paid to the fork travel. 4. Used for different types of off-road bikes: Quick release is used for XC, road bikes, etc., while thru-axle is used for high-intensity off-road biking like AM, FR, and DH.
I remember being confused about thru-axles and quick releases when changing my bike wheel for the first time. A thru-axle is essentially a bolt that runs through the frame and hub, requiring a wrench for installation and removal—slower than a quick release but rock-solid stable. It won't loosen or misalign on bumpy roads, so even when bombing downhill on my mountain bike, I never worry about the wheel flying off. As for quick releases, they use a lever mechanism—just click and it's off, making tire changes or roof rack mounting super convenient, perfect for urban commuting or beginners. The downside is potential wear and misalignment over time. The core difference lies in their structures: thru-axles provide even pressure, reducing component fatigue, while quick releases rely on cam-based clamping—simple but potentially uneven. After five years of off-road riding, I find thru-axles far safer, especially for disc brake systems.
As a seasoned racing driver, I'm well-versed in the performance differences between thru-axles and quick releases. Thru-axles feature a thick bolt-style design, typically 15mm in diameter, ensuring perfect alignment between the hub and frame. This enhances rigidity and handling precision, preventing wheel misalignment during descents or sprints while delivering more stable shock absorption. Quick releases utilize a cam lever for fast tightening—installation takes mere seconds—but they're prone to loosening under high stress, posing brake failure risks. Thru-axle installation requires tools and is slightly slower, but offers superior durability and reduces hub friction. Quick releases are cost-effective for training. My team has fully switched to thru-axles—they're essential for mountain trails. Safety comes first; this distinction can't be overlooked.
