Park Tool TM-1 Spoke Tension Meter for Precision Wheel Maintenance
Achieve professionally built, high-performance wheels from your own workshop with the Park Tool TM-1 Spoke Tension Meter. A fundamental tool for any cyclist or mechanic serious about wheel performance and longevity, the TM-1 removes the guesswork from wheel building, truing, and repair. Proper spoke tension is the secret to a strong, reliable, and durable wheel, and this precision instrument is the key to mastering it.
The TM-1 Tension Meter accurately and reliably measures the absolute tension of each of the spokes in a wheel, as well as the relative tension between all the spokes in a wheel. Easy to use and priced affordably, the TM-1 works on nearly any bicycle spoke—no matter what the diameter, material, or shape. The TM-1 is for anyone building or truing wheels, diagnosing wheel problems, or assembling new bikes. It’s a tool that belongs on every workbench.
Build Stronger, More Reliable Wheels
Investing in proper wheel maintenance with the TM-1 provides immediate and lasting benefits for any rider. By ensuring consistent and correct tension across all spokes, you can significantly improve the quality and performance of your wheels.
* Enhanced Durability & Performance: Properly and evenly tensioned wheels are substantially stronger, stay true for much longer, and resist fatigue, providing a safer, more predictable, and responsive ride.
* Accurate Wheel Diagnostics: Quickly get to the root of persistent wheel problems. The TM-1 helps you identify spokes that are too loose or too tight, allowing for precise adjustments that solve issues like chronic wobbles and rim cracks.
* Confident Wheel Building: Build professional-grade wheels from scratch with absolute confidence. The TM-1 provides the data you need to ensure each spoke is correctly and evenly tensioned according to the rim and hub manufacturer´s specifications.
* Essential for Carbon Rims: Especially critical for carbon rims, which are less forgiving of uneven tension. The TM-1 helps prevent costly damage by ensuring a balanced and uniform tension load.
Main Features: Engineered for Accuracy and Ease of Use
The Park Tool TM-1 is thoughtfully designed to deliver consistent, reliable results for both professional shop mechanics and home enthusiasts.
* Universal Spoke Compatibility: Its versatile design works flawlessly with virtually any type of bicycle spoke, including standard round, bladed/aero, and spokes of different materials and diameters.
* Precise Absolute Tension Measurement: The TM-1 allows you to accurately measure the absolute tension of each individual spoke, ensuring you are building to specific manufacturer recommendations.
* Critical Relative Tension Analysis: Effortlessly compare the tension between all the spokes in a wheel. Achieving uniform relative tension is the most important factor for a wheel that is strong and stays true.
* Simple, Ergonomic Operation: The tool is designed for efficient, one-handed use, allowing you to comfortably hold the wheel and quickly check every spoke.
* Easy-to-Read Analog Gauge: The clear, intuitive gauge provides a simple numerical reading based on the spoke´s deflection, which is then used to determine the actual tension.
* Comprehensive Conversion Chart & App: A durable, printed conversion table is included to easily convert the tool´s reading into kilograms force (kgf). For the most up-to-date information, the TM-1 also works with the online Park Tool Wheel Tension App.
