I’ve been having issue with my Force rear derailleur for a few weeks now
It seems to have developed the annoying habit of burning through batteries super quickly (<1 ride) and then bricking the battery. Contacted SRAM who advised me to try to jump start the batteries (power cycling the charger). This worked to revive a few of them (I’ve been through about 5 batteries as I assumed it was battery issue initially). I then reinstalled the firmware.
I’ve just now noticed that when shifting up the cassette the derailleur flashes green then red if I ask for it to shift up the cassette 2 cogs (i.e. 2 gears easier) and only allows 1 cog shift. No issues going down the cassette, green flash then shift with 2 cogs harder
Has anyone experienced anything similar? The derailleur is less than 6 months old so should be warranty-able if it’s defective but want to check I haven’t missed anything obvious
