Not all bike frames have threaded mounting points for a luggage rack at the bottom. However, if your bike has a modern thru-axle, this special axle, which replaces a standard thru-axle up to 180 mm, solves the problem. It features threads at the ends for M6 bolts, and the included spacers allow for length adjustment. Once the axle is installed, youll have two sturdy mounting points available. Note! This axle model has a thread pitch of 1 mm. Check your bikes axle thread pitch, as there are three options available: 1 mm, 1.5 mm, and 1.75 mm thread pitch. The package includes one axle. The first additional image shows the contents of the package, while the second image, for comparison, displays all available thread pitch versions.
