Nitto Stem Spreading Tool

Using a screwdriver to pry open a stem clamp often leaves deep gouges in your handlebars or the stem itself. This tool is designed to apply even, controlled pressure, which protects your components' finish and prevents structural damage.

It is designed for standard quill stems and similar bar clamps where the gap needs to be widened to slide the handlebar through. It may not be compatible with stems that use a faceplate design or those with very tight, non-standard clamp tolerances.

Not at all. It weighs 137g and is compact enough to fit easily into any standard bicycle tool roll or drawer without taking up significant space.

While the tool is made of durable steel, it is designed to be used carefully. As long as you don't force it beyond the necessary width to clear the bar, it is far safer and less abrasive than using hardened steel tools like screwdrivers or pry bars.

Because it is a simple, high-quality steel tool, it requires virtually no maintenance. Just keep it clean and dry to prevent surface oxidation, and it will last for many years of shop use.
