This is the Park Tool TM-1 Spoke Tension Meter. 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 spokeóno matter what the diameter, material, or shape. The TM-1 is for anyone building or truing wheels, diagnosing wheel problems, or assembling new bikes. Itís a tool that belongs on every workbench.
The TM-1 Tension Meter includes a printed table to convert tension reading to kilograms force. Because of new and varied steel bladed aerodynamic spokes, there is a webpage that acts as a chart calculator for steel bladed spokes not on the table. See the TM-1 Tension Meter Bladed Spoke Calculator here
Also see the Wheel Tension Balance web app here
. This page will help the user quickly convert tension readings to kilogram force pull, and also provide a graphic chart of relative spoke tension.
