As a quick-release assembly suitable for both road and mountain bikes, its core advantages lie in its differentiated front and rear design and compatibility with multiple specifications. The front quick release is designed for a standard 100mm fork spacing, with a length tolerance of ≤0.5mm, ensuring smooth passage through the hub axle and a snug fit. The 44±15g weight is achieved through an optimized shaft diameter, making it 12% lighter than a similarly sized heavy-duty quick release. The rear quick release is available in different sizes, with a 130mm shaft suitable for road forks, 135mm/142mm for conventional mountain bikes, and a 148mm shaft specifically designed for Boost-spec mountain bikes. The 49±15g weight is achieved through a thicker shaft and a reinforced locking mechanism to withstand rear-wheel drive loads and shifting torque, preventing shaft deformation over time.
High-elasticity springs are installed at both ends of the assembly. The front spring has a moderate preload (50N), while the rear uses a stronger spring (70N) due to the greater loads. Both components follow the "small end facing inward" installation principle, ensuring the quick release automatically positions and cushioning the impact of contact between the frame and the hub. Some front wheel quick releases are available with an optional safety lock mechanism to prevent accidental opening or loosening due to vibration while riding. Compatible with both disc brakes and conventional wheels, they provide reliable wheel retention for road racing, light mountain biking, and other scenarios.
Differentiated front and rear weight and strength design:
The front quick release weighs 44 ± 15g, utilizing a lightweight "7075 aluminum alloy handle + stainless steel shaft" combination, making it 15% lighter than a full-steel quick release and reducing the load on the front wheel. The rear quick release weighs 49 ± 15g, utilizing a "thickened stainless steel shaft (1.5mm wall thickness) + reinforced locking buckle" to withstand a torque load of 30N·m, 25% higher than front-wheel quick releases. This allows it to withstand the continuous load of rear-wheel drive and prevent shaft bending or locking failure.
Highly elastic springs provide both cushioning and positioning benefits:
Both front and rear quick releases are equipped with manganese steel springs. The front spring features a 6-coil design (12mm diameter) and the rear features an 8-coil design (14mm diameter). The springs offer a 95% spring recovery rate and automatically calibrate the quick release position during installation, reducing manual adjustment time. The springs also cushion the impact of road bumps on the frame and hub, preventing wear on the paint caused by direct metal-to-metal friction, thereby extending the frame's lifespan.
Anti-loosening mechanism adapts to diverse safety needs:
The front quick release features an optional safety lock assembly. Once locked, it requires a dedicated tool to unlock, effectively preventing vibration and accidental release during riding. Suitable for high-speed braking with disc brakes. While the rear quick release lacks a safety lock, the locking handle features a "double-tooth" design with a 2mm engagement depth, improving anti-loosening performance by 30% compared to a single-tooth design.This makes it suitable for the frequent speed changes and bumpy terrain of mountain cross-country riding.
Corrosion-resistant and durable, suitable for harsh environments:
The shaft is galvanized and passivated, and passed a 48-hour salt spray test without rust. The handle is matte anodized, offering a 50% higher anti-slip coefficient than polished handles, making it easy to tighten and remove even with gloves. Suitable for use in rainy, muddy, and other harsh riding conditions, the maintenance period is extended to 12 months (compared to 6 months for conventional quick-release shafts).
Application areas for Quick Release :
Daily Road Ride and Training/Light Mountain Bike/Boost-Spec Mountain Bike Specialty/Multi-Model Club Equipment: With a wide range of specifications and differentiated designs, these shims are suitable for clubs to purchase in bulk or individually. These shims can be flexibly configured based on the member's bike type (road, mountain, or boost). An optional front wheel safety lock caters to novice users, while a robust rear wheel design is suitable for advanced off-road users. Consolidated purchasing reduces equipment management costs.
