EW-WU101

Brand: Shimano

D-Fly wireless unit of 11-speed Di2, wired in parallel between two E-Tube cables and hidden in the frame or along a seatstay. It broadcasts gear position, battery level, adjust mode, suspension mode and shift mode to a cycle computer, over Bluetooth LE and ANT private. Shimano notes that ANT private talks to ANT+ computers without being an open profile. Dropped from the catalogue in 2020 in favour of the EW-WU111.
