The free spoke tension graphing tool I’ve hosted online since 2013 has been re-homed to islandix.com/radar. Please update your bookmarks.
This tool is also available with Wheel Analytics under the name Tension Radar. When used with the Islandix ecosystem, you are independent of the cloud (functions without internet access). It works with your Islandix FP-2 foot pedal and supports custom tensiometer calibrations.
