• Maybe current Ultregra then?

    I don't want the full group. It'd just be shifters, cables, battery, junction, deraillers.

    I really want to tear down my Mason and Kinesis and build a single bike with road and gravel wheelsets. Then I could use all the spare parts to convert her bike to Di2.

  • yeah a mix of grx and ultegra maybe as the grx front mech will allow for cheaper/shimano sub compact

  • That's what I've got on my road bike (shimano GRX sub-compact, 30-46). It actually works with ultegra front mech.

  • Did I imagine it or does GRX not have a road q-factor? Are GRX double cranks wider than road cranks?
