The TM-1 Tension Meter accurately and reliably measures the absolute tension of each of a wheel's spokes, as well as the relative tension between all of a wheel's spokes. Easy to use and affordably priced, the TM-1 works on almost any bicycle spoke, regardless of diameter, material or shape. The TM-1 is for anyone building or making wheels, diagnosing wheel problems, or assembling new bikes. It's a perfect tool for any workbench.

NOTE: The TM-1 Tension Meter includes a printed table for converting tension readings into kilograms of force. For steel spokes that are not on the printed table, you can generate custom conversion tables using the Wheel Tension app. The app also provides an interactive tool to view and analyze relative spoke tension.
