As much as we’re obsessed with weight; we know the old adage rings true – Safety First. OVERFAST thu-axles have undergone years of research, development & testing. Throughout development one thing was paramount; there would be no compromise to safety. While some manufacturers have experimented with bonding aluminium threads to carbon thru-axle shafts, our patented technique relies on a mechanical interface between the carbon and alloy components. While we also use aerospace-grade adhesives to bond the two, the adhesive is just for added peace of mind. Even without the adhesive, our thru-axles have a tensile strength of 500kgf. With the adhesive the overall tensile strength of the thru axle is over 900kgf

OVERFAST testing includes the following:

• Thru Axle Fatigue test with wheelset (EN Standard)
• Thru Axle Impact test with wheelset (UCI Standard)
• Maximum Torque Test (19Nm)
• Maximum Tensile Strength Test (>950kgf)
• X-Ray Inspection Test
• Lateral Compression test. ( 100-200kg)
• Carbon Cap Impact and Fatigue Resistance Test. (20j impact, 12Nm torque installation and disassembly for 200 cycles a 1 minute intervals.)
• More than one year real-world testing. (WuBo, 80kg Taiwanese Sprinter)
