Highlights
Why we rate it
Made for 12-speed Di2
Uses the slim, water-resistant SD300 plug shared by Dura-Ace R9200, Ultegra R8100, 105 Di2 and GRX RX825 Di2.
Internal routing
The I version is designed to run inside the frame from the battery to each derailleur.
Wide choice of lengths
From short 150mm links up to 1400mm runs for fully wired lever installs on larger frames.
Spare for rebuilds
A sensible part to have in stock when swapping frames or replacing a pinched wire.
