Will the TSA allow bike parts in your carry on? Has any one tried flying with disc brakes, (mechanical), handle bars, pedals, a crank set?
Has anyone been told do not pass go with your bike parts? I am referring to domestic flights in the USA.

Which bike parts are allowed on a plane? Which bike parts are allowed on a plane? Which bike parts are not allowed on a plane?
How do you know, did you try it, or make a guess?
