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.


  • The TM-1 Tension Meter includes a printed table to convert tension readings to kilograms force.
  • For steel spokes not found on the printed table, you can generate custom conversion tables using the Wheel Tension App.
  • The app also provides an interactive tool to help visualize and analyze relative spoke tension.
