Finding it unreasonably difficult to replace the front mech cable on my 2017 Arkose 4.
Removing the original Jagwire cables (they’ve lasted well), the thin plastic cable outer that you see under the bototm bracket snagged on the PTFE cable coating when I tried to pull through, so I had to throw it away.
“Oh well”, i thought. I have other bikes with similar routing and they don’t have that plastic outer. Must be a Jagwire thing.
Now I’ve tried to set up the front mech, I can’t seem to get enough tension on the cable to change up into the big ring. I’m doing the usual – drop into small ring, pull cable with pliers, tighten bolt.
So I guess:
1. Is that plastic outer important? And if so, what’s it called / where can I get more?
2. I just poked the replacement cable through the downtube until it came out the bottom. Could it have caught on something in there? I suppose in theory it could be wrapped around the rear mech cable / brake hose which is giving it extra slack when I change gear. It doesn’t feel that way though.
Any other ideas gratefully received. Bike fettling time is at a premium (small child!).
