  1. Thanks for posting this interview. This is one of the most helpful videos I have seen. I especially appreciated the explanation for why the 48/31T crank was chosen. I’ve been using a 46/30T White Industries crank for a few years with my otherwise Ultegra Di2 setup, along with a 11-34T cassette, and 38mm Compass tires. On a whim, I recently purchased the 46/30T GRX crank, and managed to get it working with the Ultegra (band-clamped) front derailleur, despite the chain-line. I was hesitant to get the 48/31T crankset, because I didn’t want to change too many things at once, but now I realize I might have been better off. (The $150 GRX 46/30T shifts better than the White Industries crankset did, FWIW.)

  2. Hi Jom,
    I have a stock Raliegh Roker Sport – which I bought some time ago after I saw your video extolling it’s virtues. It still has the original Tiagra group set. So I’ve kind of been toying with he idea of upgrading to a Shimano di2. I’m wondering if now that the GRX group set has appeared whether this would be something to go for.

    Any thoughts? On one hand I wonder wether to put that much time and effort and money into this older bike (2017) is a good idea, but maybe much less expensive to add these upgrades than going for a new expensive bike. Plus I’m thinking if I do build a new bike someday, I can move these components to the newer bike.

    Am I barking up the wrong tree here? Or, is this a reasonable project?

    Thanks!

    Tom

  3. I wish there had been discussions about why a product is announced but not readily available for 4 months after the initial announcement. As a shop employee this really creates a pickle for the shop and the consumer and Shimano isn’t helping.

    1. I too find product announcements frustrating. My Niner is waiting on GRX DI2 and Easton 47/32 chain rings and carbon cranks for several months.
      I don’t even want to talk about how long I been waiting on my 2020 Pivot Mach 4SL

  4. And yet, Niner, in their infinite wisdom have decided to do this to their $5300.00 2020 RLT 9 RDO 5 star Shimano “GRX 800 2x” build … “CRANKSET EASTON EA90 47X32T” SMH!

      1. JOM – That’d be great if you could do that. The build spec on the RLTs are really mysterious. Putting a $120 MSRP crank on a $5000 build is silly. Not to mention because of that they’re not putting the GRX FD on the bikes. Heck half of the “GRX drivetrain” isn’t even GRX.

        If Shimano is so constrained to where manufacturers are having to go 3rd party, that’s really unfortunate. But cutting corners to keep margins in check, well, that’s equally as unfortunate.

        I was stoked to pick up a 2020 RLT 9 Steel, cash in hand, but with the build specs and price points I’m actively pursuing alternatives.

        1. I ride my 2019 RLT Steel every day. It’s a joy to ride. IMO, buy the bike, be real patient, and you’ll end up a very happy guy 😎

          1. Jim – Thanks. I’ve already got a 2018 4-Star that I love. But I was real interested in a 2020 4-Star for GRX and to be able to use my Hunt Dynamo wheelset. It’s currently much cheaper to go frameset and build it as a proper GRX build.

  5. I don’t really believe the answer regarding the Ultegra RX800 rear mech. It’s no longer listed on Shimano website, so I suspect they have actually killed it as some had predicted.
