Rugged, lightweight, and advanced, the EMT Pro MTB tool provides security in ever-changing terrain. It includes a wide range of Allen keys, a screwdriver, a chain breaker, and much more—it even comes with a disc pad separator. For durability, the side plates are made from forged aluminium, while the bits are chrome-plated to make them rust-resistant. And to keep the overall weight down to about 104 grams, we even hollowed-out the core of the Allen keys.
