The BLACKBEARING TR-1.0-1 trailer axle is a specialized component designed to ensure the secure attachment of bike trailers on frames equipped with Ø12mm rear dropouts. CNC-machined from black anodized aluminum, this thru-axle offers an adjustable length from 171 to 183 mm thanks to the included spacers and support cones, ensuring optimal compatibility with the majority of market standards.

Design and Manufacturing

BLACKBEARING deploys its expertise in precision CNC machining to produce aluminum axles with strict tolerances. The M12x1.0 threading (1 mm pitch) ensures smooth threading and reliable mechanical strength. The black anodization protects the material against corrosion while providing an elegant and durable finish. Specifically designed for bike trailers, this axle incorporates the manufacturer reference AX-TR-1.0-1 for quick identification.

Versatility and Adjustments

• Variable length: range from 171 to 183 mm to adapt to different rear dropout widths and trailer systems (Thule, Croozer, Burley, etc.)
• Modular support system: included spacers and cones allow for conical or flat support depending on trailer requirements
• Wrench installation: precise and controlled tightening, avoiding risks of loosening during use
• Universal compatibility: Ø12 mm frame standard, M12x1.0 threading common on many trailer models

BLACKBEARING Trailer Axles Range

BLACKBEARING offers a complete range of trailer axles covering different threading standards and lengths. Each model is identified by its "TR" (Trailer) reference followed by the thread pitch and a version number, making it easy to choose the right axle for your equipment.
