The tool you need for building wheels.
Building your own wheels or replacing spokes
can be an easy and rewarding experience. A trueing stand may be the
first tool you need to achieve this, but the Park Tool TM-1 Spoke
Tension Meter is a close second. The TM-1 gives you accurate and
reliable measurements on nearly any bicycle spoke -- regardless of
diameter, material, or shape. It measures the absolute tension of each
of the spokes in a wheel, as well as the relative tension between them.
The TM-1 is a tool that belongs on every workbench.
