This is an incredibly compact and portable chain tool. It's a full-metal folding tool with 7 functions. It can easily slide into your MTB bottom bracket, so you can access it whenever you need. Built-in magnets ensure the folding tool stays securely in place. For cyclists who prefer to ride without a bag or pack, this stealthy multi-tool is an excellent choice.


Using this multi-tool is a breeze. Just slide it out from your MTB bottom bracket when you need to use one of its 7 functions. Whether it's making small chain adjustments or doing other minor repairs, it's up to the task. When you're done, slide it back in and the built - in magnets will hold it in place. As for maintenance, keep it dry and clean. Wipe it down after each use to prevent rust and damage. If you notice any parts starting to wear out, it might be time to replace them. And always handle it with care to avoid any accidental damage.
