Hi, this is for those with experience of a CAAD12 over a long period.
I’ve totally recabled the whole bike after a few years use. I am getting sticking from the rear mech cable that’s baffled me, and wondering if the frame has worn inside and Is binding the cable.
The rear mech cable will slide down the right side downtube hole freely. If I then shift (as the cable pulls) the cable binds up and needs a pull from the mech end to release itself.
If slide in by hand you get the same effect, slides down the tube fine but pulling up it binds. A slight slide down releases it.
It has always been cabled right shifter into right side downtube hole and has had the ferrule on the cable outer. It has the outer teflon sleeve around the plastic bracket and the cable is routed under and away from the BB/crankset. The shifter works absolutely fine. I test cabled it up on the left side downtube hole to check and it shifted up and down fine (same shifter, mech, cable and outer). Cable is nowhere near the bottle cage rivnuts/bolts (had this issue with no cages fitted).
Can a groove wear inside the downtube hole where the ferrule goes which then catches the cable? Has anyone experienced this before with a CAAD12? Is there anything I am stupidly missing?
Thanks in advance.
