The brand new Wahoo Elemnt GPS computer just added integration with SRAM eTap and Shimano Di2 electronic drivetrains, plus fields for muscle oxygenation for third-party sensors from BSXInsight and Moxy Monitor.
With a firmware update, the Elemnt can show real-time gearing information for eTap and Di2 in graphic and/or numeric form, along with battery status for the electronic drivetrains.
Shimano 9070 Dura-Ace Di2 users can use the Di2 hood buttons to control the Elemnt, by changing pages, starting and stopping laps and zooming in and out on pages.
For muscle oxygen sensors like BSXinsight or Moxy, the Elemnt can now display current, average, minimum and maximum values for SmO2 (muscle oxygenation) and tHb (total hemoglobin) metrics.
