The key to a stable and durable wheel is correctly and evenly centered spokes. The TM-1 tension meter measures the spoke tension of each individual spoke and, in addition, the relative tension of all spokes in a wheel accurately and reliably. Easy to use and affordably priced, the TM-1 is universally applicable to almost all spokes. Diameter, material, or shape do not matter. A must-have for any mechanic who builds or maintains wheels, whether professional or hobbyist. It should not be missing from any workshop. Includes a reference table for easily converting the measurement data into actual tension values for nearly every type of spoke.
