Sorted inner gear cable replacement. The bike is only 5 months old so left the outer cable in situ. The inner cable had started to frey on the inboard side of the clamp at the derailleur. Suspect this clamp has been over-tightened when installed on the new build.
Now I’m happy, new inner, “cable magic” lube applied to inner when feeding into the outer, new outer ferrules and a blue anodised crimp to match the pedals......Sweet
Don’t get that attention to detail at your LBS.
thanks for all info ?
