Hurricane Components QR15 Fork-Up Adapter
The QR 15 Fork Up adapter 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.
Kinda pricey. Does its job well
Well made fork adapter...no issues with attaching to my existing bike rack system and is a perfect fit for my fork. Great price as well.
