Chronos and Fenix 5 have had an interesting beta update to their firmware (details here)
Changes made from version 15.10 to 15.31:
- Added support for connecting to a shifting sensor (Sram Etap or Di2 bike) that supports up to 4 front and 12 rear gears.
Fixed an issue where steps were not being counted during a multisport activity.Fixed an issue where one wasn’t able to search near a waypoint.
Is this paving the way for 12-speed Di2 on a Shimano-based road bike? ie might this herald Garmin getting all their models in line for a Spring launch of something new from Shimano.
Sure I know Shimano already do 12-speed off-road and that 12-speed is supported by SRAM RED ETAP. And yes higher-spec Garmins (like my 945) already have (probably the exact same) Di2 support. Yet I’m not sure if Di2 officially works on any 12-speed system. Maybe it will soon? Maybe this is Garmin getting all their ducks in line for an impending release? (eg more work on the 530 firmware regarding 12-speed here too)
Maybe. Clutching. Straws. Slow News Day?…apart from Apple and Polar H9 and Circular Ring

My favourite kit and nutrition
- Maurten — the race nutrition trusted by elite athletes. Gels and drink mix engineered to be easy on the stomach.
