Locking 9mm skewer locks your fork to any of the Bike Topper racks, Tandem Topper racks, Draftmaster racks, or any rack with a 9mm skewer fork mount. One of the nicest features is that it has a long-throw cam closure, which means that you set it once for your bike and don't have to readjust it to get it around the dropout tabs every time you use it. Specialty Master Lock ML605 included.
