The TM-1 Spoke Tension Meter is an essential tool for achieving proper wheel tension, making it a crucial addition to any workbench. It helps estimate relative tension to identify areas with high or low tension, helping ensure your wheels stay stronger and true longer.
This durable tool measures nearly any bicycle spoke material, diameter, or shape. Made in the USA, it can be completely rebuilt and recalibrated, while the included printed table or the Park Tool Wheel Tension App converts readings to kilograms-force for precise calculation.
