The front handles and rear handles are interchangeable as they are the same product. However, it is important to note that a rear platform must be purchased and installed before handles can be installed on the rear end of the Micro Pro and Mini 2. It is also important to note that handles are sold in a pair, so if you would like to use handles in the front and rear of your Micro Pro and Mini 2, you must purchase two sets of handles. The Micro Pro/Mini 2 Handlebars provide more stability so you can handle each Lagree move with precision. The Micro Pro/Mini 2 Handlebars will allow you to practice and achieve more Lagree moves than you would be able to without them.
