Engineering Highlights

Patented Carbon-Alloy Interface

The critical load-bearing interface between the carbon shaft and aluminium threaded section uses a patented mechanical bonding structure. This prevents separation under torque and tensile loads. Overfast also uses aerospace-grade adhesives to bond the two for added peace of mind. 

Titanium Insert

Titanium reinforcement for the hex wrench socket adds only 1g but significantly improves thread durability and long-term reliability.

Weight Savings

Saves ~100g compared to many stock thru-axles, depending on model.


Strength & Safety Testing

Each design passed both destructive and non-destructive testing, including:

  • 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.

Assembly Information

  • Do not use RSP assembly paste. It may cause thread seizure.
  • Light marks on threads may be visible due to QC torque testing. Rest assured that all axles are brand new. This step is essential to guarantee the safety of the product.
  • Ensure the head of the tool is inserted at least 15mm into the thru-axle before tightening/loosening.
  • Use a torque wrench for installation. Recommended Torque: 7-9Nm
  • Tighten by hand initially to ensure the thread between the thru-axle and frame is aligned to prevent stripped threads.
  • Overfast uses a tighter thread tolerance, so please expect a tigher fit during assembly compared to stock axles.

Warranty Information

Warranty Coverage

All Overfast products are covered by a 2-year warranty against manufacturing defects. This warranty does not cover damage caused by misuse, accidents, crashes, improper installation, modification, or normal wear and tear.

Warranty Claims

To process a warranty claim, customers must provide clear photos and/or videos showing the issue. Once the claim has been reviewed and confirmed by Overfast, replacement parts will be arranged as quickly as possible.

Thru-Axles

For defective thru axles, please provide clear photos or videos of the affected product. Once the defect has been verified, a replacement will be shipped promptly.

Cranksets

If a crank arm suffers a confirmed manufacturing defect (non-user-related), please provide detailed photos and a description of the issue.

After approval:

- The defective crank arm must be permanently destroyed (for example, by drilling a hole through it).
- Evidence of destruction must be submitted.
- If only one crank arm is defective, only the affected side will be replaced.

Once the above requirements are met, the replacement will be arranged immediately.

Wheelsets

Warranty service for wheelsets depends on the specific component that has failed. After inspection, Overfast will provide the appropriate replacement part or component based on the confirmed issue.

Other Products

The same warranty process applies to all other Overfast products. As long as sufficient evidence is provided to verify a manufacturing defect, warranty claims will be prioritised and processed promptly.

----------------------------------

Crash Replacement Programme

For products damaged due to crashes, accidents, or other user-related incidents, Overfast offers a Crash Replacement Programme.

Eligible customers may purchase a replacement product at 30% off the recommended retail price (70% of MSRP).

----------------------------------

Notes

- All warranty claims are subject to inspection and approval by Overfast.
- Clear photos, videos, and any other requested documentation may be required before a claim can be approved.
- Overfast reserves the right to determine whether a claim qualifies under the warranty or the Crash Replacement Programme.
