• Yes it would. There's just enough space in a T47 BB shell with an external bearing BB to squeeze a hydraulic brake line around the BB shell, depending on which make of BB you use. It's tight, but it's just possible.

    If they were using a lugged BB shell I could understand it as there are no lugged T47 shells. But for a full fillet-brazed BB shell it's a bit of an odd one.

  • it's a custom bike. The owner probably requested it.

    Still, with the CK sleeve for 30mm spindles, hydraulic lines won't fit in there.
