OVERFAST Ultralight Thru Axles
The OVERFAST Ultralight Thru Axles are designed for riders who obsess over the details. While most bikes ship with heavy steel or alloy axles, OVERFAST focuses on reducing weight in one of the most overlooked upgrade points. With claimed weights starting around 30 grams per pair (depending on specification), these axles offer a simple way to shed grams without changing your drivetrain, wheels, or cockpit.

- High load capacity: tensile strength rating exceeding 950 kgf.
- Wide fitment range: multiple lengths and thread standards available to match most modern disc-brake road frames.
- Latest generation design: updated version introduced in the 2024 production run.
