Genuine Burley 12 x 1.0 thru axle adaptor, suitable for attaching Burley cycle trailers to bikes with a 12mm thru axle. * Used but in good condition. * Fully functional with normal signs of use. * Genuine Burley part. * Fits bikes with a 12 x 1.0 thread and 142–148mm rear hub spacing (please check compatibility with your bike before purchasing). * Ideal replacement or spare axle for Burley child trailers and cargo trailers. Only selling as I no longer use the trailer that this was purchased for. Thanks for looking
