Product Information

Full details

The Park Tool MT-40 is an essential companion for cyclists who need a reliable, compact solution for trailside or roadside mechanical repairs. Designed for riders who prioritize preparedness, this multi-tool packs a comprehensive suite of wrenches and drivers into a rugged, ergonomic frame. While its robust forged aluminum construction offers excellent durability, users should note that at 243 grams, it carries slightly more weight than ultralight racing-focused tools.

Can I use this on E-bikes?

Troubleshooting

Tools are difficult to deploy or feel too loose

Tighten or loosen the side pivot bolts using a hex key until the desired resistance is achieved.

CO2 inflator is not seating properly

Ensure the cartridge threads are clean and free of debris, then screw the cartridge firmly into the adapter.

Surface oxidation or minor rust spots

Gently scrub with a soft-bristled nylon brush and a light penetrating oil, then wipe clean with a dry cloth.

Setup, Compatibility & Care

The MT-40 requires no formal setup; it is ready to use immediately out of the box. Because the tool bits are made from hardened and plated steel, they are highly resistant to rust, but it is best practice to wipe the tool down with a dry cloth after use in wet or muddy conditions. Periodically check that the pivot bolts on the side plates remain snug; if the tools feel too loose or difficult to flip out, use a corresponding hex key to adjust the tension of the pivot screws. Avoid using harsh chemical solvents, as these can strip the protective finish on the aluminum frame.
