I like ! Two thumbs up !!
There might be other (better ?) options than the RS700 11 spd shifters - but I'm not aware of them.
Questions:
Why did you go with the GRX calipers ? ( instead of XT or 105 or Ultegra or whatever ?)
What brake lines were installed from the factory ? Did you change the brake lines ? And if so did you go with Shimano BH59 or BH90 lines ?
Thanks !
I went with the GRX 810 calipers because I found them on sale and was able to combine the sale price with a coupon code.
XT would not work unless you used an adapter to convert from post mount to flat. The FX Sport uses flat mount calipers. I *think* XT and XTR are all post mount.
The bike came with BH59 brake lines and they were just re-used for the upgrade.
