The Pro Loop is better suited for riders who have reached a level where unhooked maneuvers are part of their routine (so-called “unhooked riding”). The large loop makes it easier to re-hook. Like the longer Chickenstick, this longer Pro Loop is available separately as an optional accessory.
Note on installing the loop: The grub screw used to secure the loop should only be tightened until the surface of the screw is flush with the white surface of the quick-release. If you tighten it too much, it could press against the axle from the inside.
