Hurricane Components QR15 Fork-Up AdapterThis new addition to the Hurricane Fork Up product line is designed with the same quality as the rest of the Hurricane products. The Sequel 15mm is designed to work with most 15mm suspension forks and installs quickly and easily on your fork before loading it onto your rack. Simply remove your wheel from your front fork, slip your 15mm axle through the Fork Up, install as you would your wheel and tighten your QR skewer (or axle) to the Fork Up. Finally, place your bike onto your rack putting the bottom of the Fork Up onto the 9mm rack skewer and tighten in place. That's ...now you have a quick, safe way to transport your bike on your existing rack.
