If you know what a doohickey is, you should buy this shirt because you belong to a special group of people who are too poor to own nice bikes, but have enough time and tens of dollars to put into fixing something that might go wrong. If you don't know what a doohickey is, you should still buy this shirt, and come up with your own explanation of what it is, and how you fixed it. Also, see if you can get that person to buy your new patent-pending fix that you are selling, and send me only 10% of your profits.
We want you to love your order! If for any reason you don't, let us know and we'll make things right.
Don’t love it? We’ll fix it. For free.
