The ZTTO internal frame cable damper foam sleeve is a cheap, functional solution for quieting internally routed brake lines, with one reviewer paying €2.79 (€5.58 after shipping/customs) versus roughly €9 for comparable damping on Amazon. It does the job of preventing rattle, but installation is fiddly and the routing connector can come off while pulling the line through, requiring tape and soapy water.

Reviews & Ratings
34:27The reviewer does not discuss cable insulation as a distinct bike part. The only related mention is the use of electrical tape (Isolierband) as a makeshift fix: he wraps a bit of tape around the brake line and the internal routing connector so they stay together and slide through the frame as one piece, and he also tapes the brake line to the fork to prevent rattling.
