OK - If you want a quick tweak of your Matrix trucks but don't have your complete tool kit on you or you don't want to carry hex keys in your pockets try taping a 4mm hex key to the top of your deck. It's kind of ghetto but it has helped me out at many races. Especially when you are just trying to dial in a course and you don't know if you need a really stiff setup or a more maneuverable set up.
So the next time your at the start gate and need to make that last little tweak you can do it quickly.
