Garmin Edge MTB#
Mountain-bike-specific GPS cycling computer. Garmin’s first head unit purpose-built for off-road riding — combines full-colour maps, MTB trail data, and MTB-specific metrics with the ANT+ sensor ecosystem.
In the Grizl PAN, the Edge MTB is the primary data recorder and the central ANT+ hub, aggregating data from all on-bike sensors into a single .fit activity file.

| Shimano GRX Di2 | ANT+ (D-Fly) | Receives gear position & battery |
| Garmin Varia RTL515 | ANT+ | Receives radar alerts |
| Watchlink | ANT+ | Transmits aggregated data to Apple Watch bridge |

Recorded Data (.fit file)#
Every ride produces a .fit file containing:
- GPS track (5 Hz)
- Power (from Favero Assioma Pro MX)
- Cadence
- L/R power balance
- Gear position (from Shimano GRX Di2)
- Di2 battery level
- Radar events (from Garmin Varia RTL515)
- Heart rate (if HR sensor paired)
- Elevation (barometric altimeter)
- Temperature
Buttons#
The Edge MTB uses 7 physical overmolded buttons (no touchscreen) — designed to be operable with gloves or in wet conditions.
