Shimano kindly invited me to their GRX Media camp in beautiful Whitefish, Montana, for several days of riding, tech talk and more.

In this video, you’ll hear about some of the concepts behind GRX Di2, see my first rides on the GRX Di2 groupset, the finer details, impressions and so forth. In particular, shifters, derailleurs and the sub brake levers are covered, along with everything else in the groupset.

This particular GRX groupset was installed on a Pivot Vault (see the link below for details of that frame and fork) with a full complement of Shimano Pro cockpit parts, etc, to be ridden and reviewed long term. Additionally, there will be a Montana ride experience video coming later.

  1. JOM, do you have any intel if 817 rear derailleur will actually work with 2×11 setup? I know it designed for 1×11, but wondering if it will. Currently have R8070 on my Lynskey GR PRO with Rotor 46/30 front and 11/42 rear, RX805 does work but wish cage was a little longer

    1. Can’t speak to the 817RD, and am curious myself. I went with the 815 to go with my FSA 46/30 or 48/32 combo. For me it is better to walk when the 30/34 fails me lol. I can say upgrading to the GRX FD was worth it as it got rid of the chain rub at the extreme ends of the cassette that I could never adjust out of the standard road FD. I also noticed that the Di2 software offers me a 46/30 combo as a choice now and makes for much better syncroshift experience.

    2. As an FYI, the 2x specific rear derailleur aka the 815 has the longer cage of the two, and the bigger pulleys. Knowing shimano, 34T is conservative… I will have the 2x 815 Pivot bike in my possession soon from the video (winging its way from Montana at the moment), and will test it with an 11-40 or 11-42, depend on what I have laying around… if it works, there will be video 🙂

  2. Must get the dropper lever! I have used the PNW CX lever and now have the Wolftooth. WT is clean install, but not in a place for frequent usage. Preferred the PNW/Pro components location.
