Gear Sensor

Gear sensor cutout to reduce chain tension when shifting with mid-drive systems. Installs inline with shifter cable to detect when rider is shifting gears and plugs into 4-pin ebrake connector of Grinfineon controllers to cause a temporary power cutout during the gear transition.

Works with any derailleur gear setup, but is not recommended for shift cables that are wrapped in a polymer liner as that can interfere with the shift detection. Just bare metal cables are best.
