TT / Triathlon Disc Brake Dual Control Lever
These TT / Triathlon Hydraulic Disc Brake levers have only one E-tube port each and a set of them weighs about 200g, according to Shimano.
They can only be used with Synchronized Shift, since they only have one button each. You generally set one up to shift the RD to an easier gear and the other to shift to a harder gear.
These TT/Triathlon levers are 12-speed compatible, if you update them to firmware version 3.3.0 or newer.
These shifters have to be connected to the BT-DN300 battery by wire. They will not function if there isn't a wired connection between them and the battery.
You could plug them into one of the wireless shift levers, but they won't work unless you then connect the shift levers to the battery by wire.
