OVERFAST Ultralight Thru Axles

From just 30g per pair
Carbon thru axle with aluminium thread and titanium insert
Patented mechanical bond between carbon and alloy
>950kgf tensile strength
Available for most modern disc brake road bikes
Updated 2024 version
Note: For Canyon models, MY21 comes with M12*1.0 pitch, and MY23 comes with M12*1.75 pitch. For Trek models, 2019-2021 version come with 122mm font axle, and Gen7 version comes with 118mm front axle. Please check before order.
Note: DO NOT use RSP assembling paste on these axles, it might cause the axle get jammed in the frame.
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.
Less common specifications are produced on a made-to-order basis and may require 10–15 days for production.

Ultralight Carbon Fiber Thru Axles

When we were talking about bicycle parts…We realized that almost everything is made of carbon fiber. Frame, stem, handlebar, saddles and even brake pads. But why aren’t thru axles made of carbon fiber? If we use carbon, we can reduce the weight of the thru axles by upto 60%. There were already some carbon fiber thru axles on the market, but they hadn’t become mainstream. Why not?

What are people concerned about?

Durability? Safety? Strength? Maybe people are worried about failure of the bonding. Or perhaps breaking from the excessive twisting forces. Maybe the current options weren’t light enough?

We decided to re-write the rules with our own innovative design!

Ultra Lightweight
Starting at just 30g for a pair, the OVERFAST thru-axles allow you to shave up to 100g off the weight off your bike without compromising on function or performance.

Safety First
While this is a weight weenie product, there was no question of compromising safety. 30g is well within the limits of what they could do responsibly. They tested to above and beyond industry standards again and again.

Race-Winning
At the sharp end of the peloton 100g can be the difference between winning and losing. The OVERFAST Thru Axles are a performance orientated part for the dedicate athlete who is seeking marginal gains.

Patented Technology
The unique, secure interface between the carbon shaft and aluminium locking thread was the hardest engineering problem to solve. That’s why they patented it to protect ourselves and protect you from cheap imitation products.

Product Testing

We’re always pushing the envelope for weight reduction, but we draw the line at compromising safety. Our thru-axles passed a series of both non-destrcutive and destructive testing before their official launch.

1) Thru axle fatigue test with wheelset (EN standards)

2) Thru axle Impace test with wheelset (UCI standards)

3) Maximum torque test (19NM).

4) Maximum tensile strength test (950kgf).

5) Inspection test with X-ray machine.

6) Lateral compression test (100kg, maximum of 200kg).

7) Carbon cap impact and fatigue resistance test (20J impact, 12NM torque locking, continuous twisting for 200 times at one-minute intervals).

8) More than one year athlete real world test.
