At RAD, we're absolute fans of doing things ourselves. Trying something out, doing some research and the extra satisfaction you get when you've achieved to fix something with your own hands. This is just as much part of the entire bike experience as the ride afterwards.
But, at RAD we're no fans of thought up, temporary shoddy fixes. What you do yourself, you better do well. Every time.
There are many things you can do with a hammer, that's true, but closing a drive chain can only be done properly with the right tools.
