Shipping Bicycles UPS. What UPS is looking for and all Bicycle Manufactures use is the large round plastic caps that go over and snap into the ends of both axles after the quick releases are removed. The purpose is to prevent the axles poking thru the cardboard and then cutting any thing put next to box including the UPS agent's angle or leg. I agree with the policy. Any bike store throws always lots of these and I have a lot for use when I ship. I duct tape them in place to be on safe side. I like my angles without nicks also. Charles Nighbor
