Giant Defy Advanced - Internal Cable Routing

[Deleted member 35268]

Is it likely that my GIant has internal "guides" within the frame to aid movement ?

I've been having issues with the gears not freely going down to the smaller cog.

I think when they were first replaced, the lining was bypassed.

I think there might be another lined section to the rear of the bike aswell?

You didn't say what model you have, but that won't help you if you do have a routing system (and most new bikes do) and it was bypassed, you're going to need to thread new cables through the frame correctly regardless. Unless you have the patience of a saint and nerves of steel, I think this might be a job for the LBS. Magnetic cable threading tools for internal routed cables are cheap and easy to use, but depending on your frame, they really do take a bit of a knack to get threaded correctly. However, once mastered, it's a good skill to have as paying your LBS to replace cables is a waste of good money in the long run. I managed changing internal gear cables myself, and they was through a frame with no existing cables, which is harder. You'll be faced with this problem if your cables were not setup correctly. I may have shouted a few expletives trying to getting the cables out of the finnicky holes on either end, and through the various tricky spots, the job took a significant time out of my evening, but once I understood the process, it went a bit easier.

I've got a similar aged Giant TCR and that has an internal lining for the cables - guessing they would be the same
