Oops, I never followed up on this thread, but to confirm, the braided hoses routed nicely through the frame of the CS-MB01. After comparing my brakes to my buddy's bikes, one with XT and the other with XTR, I feel really good about them. The modulation is far superior and it only took me a few days of tooling around in front of the house to be able to do controlled stoppies (rolling endo on the front wheel while slowing down). I can easily pull one about 20 feet or so. I tried it on my buddy's Niner with the XTR brakes... Bad idea and a good thing I was on the grass because I wiped out. Seems the Shimano brakes have modulation, but not a very smooth curve. They are more on/off IMO.
I've started working other simple skills, track stands, manuals, etc... Things that need highly controlled brakes. The Hope Techs are really working well in this department. Oh yeah, and I'm using a set of $20 Snail rotors from aliexpress!
Ironically, about a dozen people have tried my bike to check it out. Almost every single one of them have commented about how they like how my brakes feel.
Hopes will definitely be on my future builds.
