Why I Use It
The Park Tool 3-Way Hex Wrench is one of those tools that just lives on the workbench. With 4mm, 5mm, and 6mm heads—the most common sizes on any modern MTB—you can grab it for 90% of the bolts on your bike.
It’s faster and easier to handle than individual L-wrenches, especially when you’re doing quick checks before a ride or dialing in your cockpit setup.
Pro Tips
- Grip and speed. The T-handle shape makes spinning bolts in and out much quicker.
- Everyday essential. Keep one in your home setup and another in your race-day tool bag.
