Yup. I needed a 2.4m length and Shimano seems to only go up to 2m. Color was an added bonus. Pretty sure you can buy it anywhere, but I got it here
I’ve never used the Jagwire hydro line but so far the performance of RT-86 rotor + J02A pads + Jagwire hose is pretty meh - nowhere near the RS685 dicks on the DayRuiner.
I probably screwed up the bleed though - will try again this weekend
