The TNS-4 makes it quick & easy to install star-fangled nuts used with 1" & 1-1/8" threadless headset systems. Using a durable steel driver & built-in guide, the TNS-4 perfectly aligns the star-fangled nut & sets it to the proper depth every time. The unique design virtually eliminates pinched fingers. Replaceable set screw (#822).
TM-1 Features NOTE: The TM-1 Tension Meter includes a printed table to convert tension readings to kilograms force. For steel spokes not found on the printed table, you can generate custom conversion tables using the Wheel Tension App. The app also provides an interactive tool to help visualize & analyze relative spoke tension.
