Keep your wheels true with the S-PARTS Grade 5 titanium spoke wrench. This square spoke key adjusts spoke tension on road bike and mountain bike wheels and comes in two sizes: 3.2mm and 3.4mm. At just 15.7g, it is light enough to carry on every ride.

Key Specifications

Stronger and Lighter

Made from S-PARTS Grade 5 titanium alloy, this wrench is built for strength without the weight. At the same specification, the tensile strength of our titanium alloy exceeds that of Class 10.9 steel bolts, while its weight is close to aluminum.

Precision Where It Counts

The S-PARTS logo is stamped with a custom die, and each die is limited to 300 uses. This helps keep the tool slot accurate and strong.

Why Riders Choose It

• Strong titanium alloy for long-lasting use
• Only 15.7g, easy to carry in a tool kit or saddle bag
