Bicycle frame/fork protector for quick release frames

thingiverse

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
