• Thanks for the heads-up... sounds dodgy!

    I've actually been erring towards the GRX stuff recently as it is significantly cheaper. Even if it doesn't take Zephyr chainrings, maybe Shimano will be kind enough to keep making their 4-bolt ones for the foreseeable.

    Keep in mind you need the GRX front derailleur in this case, because of the 2.5mm wider Q-factor to make more room for bigger tyres.

    GRX double and R8000 front mech here, because was all I had. Works fine.

  • Cheers @Tijs, didn't know that. Other than the FD, do you know if the GRX chainset work with 11 speed 105? 5800 stuff can be picked up pretty cheap on ebay / facebook atm so it's quite tempting.
