Park Tool TM-1 Spoke Tension Meter

The primary purpose is to accurately measure the tension of individual spokes and the relative tension between spokes in a bicycle wheel, ensuring optimal wheel strength and durability.

Yes, the TM-1 is designed to work with virtually any bicycle spoke, regardless of its diameter, shape, or material.

Recommended spoke tensions vary by rim, hub, and spoke type. Consult your wheel or component manufacturer's specifications, or use established wheel-building resources and charts for guidance.

Absolute tension refers to the specific force (often measured in Newtons) applied to a single spoke. Relative tension refers to the comparison of tension between different spokes on the same wheel, ensuring they are balanced.

Yes, while mastering perfect tension takes practice, the TM-1 is user-friendly and provides clear readings that help beginners learn and build more reliable wheels.

It's recommended to check spoke tension after the initial build and stress-relieving process. For regular maintenance, check tensions periodically, especially if you notice any issues like a wobbly wheel or hear spoke pinging sounds.

The TM-1 itself provides tension readings. While it doesn't typically include a specific calibration chart, users can find various spoke tension charts online or in wheel-building guides based on their components.

Ensure the spoke is properly seated in the tool's jaw and that the tool is held perpendicular to the spoke. Check for any debris that might be interfering with the measuring arm.

Verify you are using the correct spoke tension chart for your rim and spoke type if aiming for absolute tension. Ensure the tool is not damaged and is functioning correctly.

Gently clean the mechanism with a dry cloth. Avoid using lubricants unless specified by the manufacturer, as they can attract dirt. If stiffness persists, inspect for damage.
