This FREE data field (with optional Pro tier upgrade) provides a simple current gear display and records gear usage metrics to your activity file for post-ride analysis in Garmin Connect. It's compatible with Shimano Di2, SRAM AXS, and other electronic shifting systems that follow the Ant+ Shifting standard. #### Free Version Features - Live gear display with current front and rear gear (ex: R10/F2) - Gear Usage Stats: Time-based gear usage distribution summaries, rear & front shift counts - Time-Series Plots: Rear/front gear index and gear ratio over time - System Info: Battery alerts and cassette/chainring tooth counts (when available) #### Pro Version Features Unlock lap statistics and power-based gear usage stats with a Pro license - available at https://eshiftmetrics.com #### Settings & Data Field Options # How should we calculate "time spent in each gear"? - Only consider moving time (requires speed data) - Only consider pedaling time (requires cadence data) - Consider all time when activity clock is running # Which developer FIT fields do you want to save? Session Fields (ie summary stats): - Rear gear time distribution - please see video explanation - % time in small front gear (2x drivetrains only) - Low eShift batteries (not supported with Di2) - Most used rear gear (by time) - % time in most used rear gear - Cassette Teeth (only shown if lowest and highest rear gear are used during the ride) - Chainring Teeth (only shown if all front gears are used during the ride) - Rear shift count - Front shift count (2x only) - [PRO] Rear gear work distribution - [PRO] % work in small front gear (2x only) - [PRO] Most used rear gear (by work) - [PRO] % work in most used rear gear Record Fields (ie timeseries data w/ graphs): - Rear gear index over time - Front gear index over time (2x only) - Gear ratio over time Lap Fields: All lap fields require a PRO license. - [PRO] Rear gear time distribution - [PRO] Rear gear work distribution - [PRO] % time in small front gear (2x only) - [PRO] % work in small front gear (2x only) - [PRO] Rear shift count - [PRO] Front shift count (2x only) #### Developer FIT Fields Warning This app can add many developer FIT fields to your activity file. Garmin limits each activity to 16 developer fields per message type (Session, Lap, Record) and 32 bytes total per message type, shared across all installed data fields. If you use other data fields that write developer FIT fields, be selective to avoid crashes. If you're only using eShiftMetrics, it's safe to enable all available fields. #### Need Help?
