couple of bike specific question and a couple of general build questions
are the bb and brake mount surfaces faced?
should you run the rear brake hose above or below the bb?
should you run a foam liner just to where the headtube starts or in the headtube as well
if you have a wired electronic sytem like di2 or erx should a liner be used on those cables as well?
- I can’t answer that because I don’t have the frame!
- Here as well, I can’t give a precise answer, but it doesn’t really change much whether it goes underneath or over the top (just do whatever works best). The important thing is to leave some extra length in the hydraulic hose so that you have the freedom to turn the handlebar completely.
- For the sound-dampening tube, I measure from the BB up to almost the top of the head tube.
- I don’t use the sound-dampening tube for electronic wires, only for hydraulic and mechanical shifting cables. However, in some groupsets (campagnolo eps) the connectors are quite large, so in those cases I put a small piece there to avoid noise.
