Product Information
OVERFAST Carbon Fiber Thru-Axles
The OVERFAST Carbon Fiber Thru-Axles are exceptionally lightweight thru-axles. These feature an aluminum threaded end with a carbon fiber body and weigh less than 30g for both front and rear axles. The head of the axle includes a titanium insert to improve durability as they are installed and removed from your bike.
OVERFAST uses aerospace grade adhesives and a patented process to bond the carbon shaft and aluminum threads together. This prevents separation under torque and tensile loads.
Additionally, OVERFAST took multiple years to develop and test these thru-axles. While weight savings are important, rider safety is paramount. OVERFAST tested their thru-axles against destructive and non-destructive tests which include:
• Fatigue test with wheelset (EN standards)
• Impact test with wheelset (UCI standards)
• Maximum torque test (19Nm)
• Tensile strength test (>950kgf)
• Lateral compression test (100–200kg)
• X-ray structural inspection
• Carbon cap impact & fatigue testing (20J impact, 12Nm repeated torque)
• 1+ year real-world athlete testing
• Threads are torqued to specification during QC inspection to ensure safety and fitment.
Note: During the QC process, the axles’ threads are tested and torqued to spec. This may result in some light scratching of the anodized threads. Rest assured, your thru-axles are brand new. This step is essential to guarantee the safety of the product.
