Does this fit the 12 speed GRX Di2 system?
Hi there, Yes this will, Many thanks Joe W
Do I need a special shimano charger to go with this lead or can it be used on any usb plug.
Hi Paul, No you can use any plug, Many thanks Joe W
Hi, does this also fit the Dura Ace R9100 Power Meter, as the USB for the 9100 has been discontinued.
Hi there, I'm afraid not, These both use different connectors Many thanks Joe W
About Shimano
Shifting the way the world rides.
From a single Osaka workshop in 1921, Shimano has grown into the world's most influential component maker. The brand's relentless engineering — Dura-Ace, Ultegra, GRX, XTR — has shaped the way the world shifts, brakes and rides, on the road and off it.
Shimano's flagship groupset, Dura-Ace, has been the benchmark for top-level road components for more than five decades. Every refinement that lands on Dura-Ace eventually shapes the entire Shimano range, all the way down to entry-level drivetrains.
