The FEE819-20 wedge support from SR SUNTOUR is an essential spare part for the Q-LOC2 thru-axle system, specifically designed for 15QLC32 axles in 15mm diameter. This component securely holds the locking wedges (wedges/pawls) that ensure quick and secure locking of the front wheel, a characteristic of SR SUNTOUR's patented Q-LOC system.

Technical highlights

• Extended compatibility: Works with 15x100mm (non-Boost) and 15x110mm (Boost) standards, offering maximum versatility for modern SR SUNTOUR forks equipped with the 15QLC32 system.
• Mechanism precision: Accurately holds the expandable wedges that pass through the axle and lock with an audible click, ensuring optimal safety with each installation.
• Preventive maintenance part: Normal wear element of the Q-LOC2 system that may require replacement after intensive use or in case of deterioration to restore original performance.
• Robust design: Made from high-strength composite material, capable of withstanding repeated tightening/loosening stresses without deformation.

Q-LOC2 system: patented technology

SR SUNTOUR's Q-LOC (Quick Lock) system revolutionizes wheel removal with thru-axle: a simple press and small rotational movement are enough to extract the axle, without tools. The FEE819-20 support plays a central role by holding the wedges that expand inside the hub, ensuring firm and secure locking in just seconds. This system offers the rigidity of a traditional thru-axle with the convenience of quick release.

SR SUNTOUR fork compatibility

This FEE819-20 support is compatible with a wide range of SR SUNTOUR forks equipped with 15QLC32 axles, including:

• AION and AXON-RLR/LOR (performance trail/XC)
• RAIDON32 LT and RAIDON-XC (trail versatility)
• XCR32 AIR and XCR32 COIL (entry/mid-range MTB)
• MOBIE25, MOBIE34 and MOBIE45 series (e-bike and trekking)

Distinction from FEE819-10 model

SR SUNTOUR offers two versions of wedge support: the FEE819-10 is intended for 15QLC TI axles (lightweight titanium version), while the FEE819-20 equips 15QLC32 axles (standard Cr-Mo version). Although their function is identical, their internal dimensions differ slightly to adapt to the specific tolerances of each axle type. It is essential to choose the model corresponding to your original axle.

Installation and maintenance

Replacing the FEE819-20 support requires complete disassembly of the Q-LOC2 axle. It is recommended to simultaneously replace the O-rings (FAA228), spring (FEP432) and retaining wire (FSS038) to ensure optimal operation. SR SUNTOUR provides detailed service videos on its official website to guide mechanics through this preventive maintenance operation.
