Park Tool TM-1 Spoke Tension Meter

Achieving a perfectly tensioned wheel is essential for strength, longevity and true running, and the Park Tool TM-1 Spoke Tension Meter gives you the precision to get it right every time. Whether you are building a new wheel or servicing an existing one, this tool measures the absolute tension of each spoke in Newtons or kilogram-force, allowing you to balance the entire wheel to within small tolerances. By ensuring even tension across all spokes you will reduce the risk of spoke fatigue, improve ride quality, and prevent costly wheel failures. Designed for use with all common spoke gauges, the TM-1 works by measuring the deflection of a spoke under a known spring load, providing quick, repeatable readings without guesswork.

- Measures absolute spoke tension from 0 to 100 kgf (0 to 980 Newtons) with consistent accuracy

- Works with straight gauge, butted and bladed spokes from 14 to 18 gauge (2.0 mm to 1.2 mm)

- Simple, one-handed operation: place the tool on the spoke, squeeze the handle and read the scale

- Durable, lightweight aluminium and composite construction for everyday workshop use

- Includes a quick-reference conversion scale on the tool body for Newton-metre equivalents

- Compatible with most front and rear wheels, including those on road, mountain and touring bicycles

The Park Tool TM-1 is the trusted choice of professional mechanics and serious enthusiasts for building and maintaining true, reliable wheels.
