Can you advise on how to route di2 cables past a bb30 rotor 3D+ power2max installed in a British bb?
TBF Sam from LMNH did it, he said it was tight but it just fit. My understanding is that he chucked a load of grease in there. It's been fine for thousands of Km.
Yes, takes some routing but is doable, ask @dammit about his time machine.
