The Park Tool TM-1 Spoke Tension Meter accurately and reliably measures
the tension of each spoke in a wheel. This information can be used to calculate
average tension across the entire wheel and achieve optimal spoke tension, leading to longer lasting and better performing wheels. The TM-1 works on nearly any bicycle spoke and the included tension chart converts readings to kilogram force depending on material, size, and shape of the spoke. For steel spokes not found on the printed chart,
you can generate custom conversion tables using Park tools free Wheel Tension App. The Wheel Tension App also provides an interactive tool to record, calculate, and display tension readings for a more in-depth analysis of relative spoke tension. The Park Tool TM-1 Spoke Tension Meter is an essential tool for any wheel building or wheel truing setup.
