From time to time tensiometer manufacturers update their conversion charts. While changing charts may seem counterintuitive, there can be good reasons to do it.
This week Wheel Fanatyk released a new chart for 2015+ tensiometers and my spoke tension visualizer has been updated in tandem. Download a copy of the latest chart from their official location. (Wheel Fanatyk is the authoritative source but I’ve mirrored the current charts as well: for original model and 2015+ model tools.) This update also includes support for 1.65mm spokes, specifically for Sapim D-Light. D-Light is supported with Wheel Fanatyk 2015+ and Park Tool TM-1 tensiometers.
As of today the conversions in my spoke tension visualizer should be up to date with current manufacturer data for all tensiometers. If you see a discrepancy, please holler.
