      Hi All,

      Can anyone suggest a solution to fixing this noise issue? Internally routed hydraulic brake cables. I think it’s the front hydraulic hose making the noise, though the rear hose may be rubbing also. The hose comes out of the fork at a bit of an angle and seems to hit the side of the headtube. If I tension the hose a bit, the noise reduces but not totally. I believe I have sufficient slack on the rear hydraulic hose.

      It just seems to me that when the hoses are routed through the handlebar, there’s enough force that makes them fairly tight in the headtube and thus makes that rubbing noise.

      Backed it out a couple times, reran the rear hose to the right (towards camera), the front hose then on the left, so the hoses are not touching, but still get this annoying noise. I don’t know if it’s wise to continue the build without fixing this now.

      Any help or ideas appreciated.

      Thanks.

      i just 3d printed external cable mounts, like channels

      the internal routing through a headset created too much resistance to shifting. damn, who invented this shit??

      You need polyurethane sleeves on the hoses if you don’t want this sound. It will require disconnecting the brakes, slipping them on, then reconnecting and re-bleeding the brakes.
