Bicycle frame/fork protector for quick release frames

For packing a bicycle - these go in place of the wheels and are supported using a normal quick release skewer. Basically, a plastic copy of your hub axle, minus the ability to work in a wheel.

Protectors that slot in can come loose on some frames, whereas these will be as secure as your wheel.

Skewers in the pics are old ones that I keep for this purpose, but you can use the ones from your normal wheels :-)

100bcd is for forks
130bcd if for most road frames, especially if with rim brakes
135bcd is for mountain bikes and most disc brake road frames
