The BLACKBEARING TR-1.75-2 trailer axle is specifically designed to hitch your bike trailer to a bike equipped with a 12 mm thru-axle (12x142 or 12x148 Boost standards). Made from high-quality CNC machined aluminum and black anodized, this axle combines lightness, strength and durability. The M12 x 1.75 mm thread and adjustable length from 174 to 180 mm thanks to the supplied spacers ensure optimal compatibility with most modern frames and trailer hitches.

• Adjustable length (174-180 mm): Adapts to 12x142 mm and 12x148 mm Boost standards thanks to the included spacers, for a custom fit.
