Shimano GRX 600 - 400 brake disc kit

[Alma]

I need hydraulic hose kit, I can see there are two types of Shimano kits BH59 and BH90 not sure on which one I need ?

My LBS told me to think of them as GRX400 = 105 group set, GRX600 = Ultegra group set.

you need the ones that have the flange connectors

SJS cycles are good for compatibility notes on items

Looking at it either would work but you would need a couple of these to connect them to your levers

Just for info BH90 are the silver ends and BH 59 the gold ones.
So I need BH90

BH90 is the nortm just make sure you get the ones without banjo joints.
