XLC QR-K01 Thru Axle for Child, Pet & Cargo Trailers | M12 x 1.0 | Syntace | 142/148 mm

The XLC QR-K01 Thru Axle is a high-quality replacement axle designed for securely attaching compatible XLC child, pet, and cargo trailers to bicycles equipped with a thru axle. To install a trailer coupling on a bike with a thru axle, the original axle must be replaced with a longer axle, allowing sufficient space for the trailer hitch.

Manufactured from lightweight yet durable aluminium, the QR-K01 features precision-printed dimensions for easy identification and installation. It is compatible with Syntace M12 x 1.0 thread standards and includes both a standard and conical 6 mm spacer for added installation flexibility.

Ideal for replacing worn or damaged axles or converting your bike for trailer use, the XLC QR-K01 offers a secure and reliable connection for everyday family rides, pet transport, or cargo hauling.
