Disc Wrench

Standard open-end wrenches can easily slip or round off the soft brass fittings found on hydraulic brake lines. The flare-style design on this wrench grips more of the fitting's surface area, providing the secure leverage needed to loosen or tighten connections without damaging them.

Yes, the integrated truing slot is designed to work with standard bicycle disc rotors. It provides the necessary leverage to gently bend a rotor back into alignment if it has become slightly warped or is rubbing against your brake pads.

It is built for both. The laser-cut steel construction is durable enough for daily use in a professional workshop, while its compact, multi-function design makes it an efficient, space-saving addition to a home mechanic's toolbox.

For most minor adjustments and trailside fixes, this tool is perfectly sufficient. However, if you are doing extensive rotor work or dealing with severely bent rotors, a dedicated, longer-handled truing tool may offer more leverage and precision.

The tool weighs 63.5 grams. While it is compact enough to fit in a saddlebag or jersey pocket, it is primarily designed as a shop tool for maintenance rather than an emergency trailside repair item.
