Sram Apex front brifter hard to shift
On my spouse's bike, the FD is very hard to shift. Just pulling on the FD cable by hand, it doesn't seem like the FD is sticky or anything. Is this a characteristic of the shifter, or something that can be treated?

How old is the bike? Does it have internal routing?
One source for increasing lever effort is inner cables that don't slide against the casing and/or other edges/surfaces along the way from the lever exit port and the der's anchor bolt. Casing liner, cable guide surfaces can get worn in a way that increases the cable's friction when under tension but feel nice when no tension is at play. Andy

It's external cabled, on a bike that's a couple years old.
Thanks. I'll take a closer look at the cabling. Also, I'll see if I can find any pictorial documentation before I crack into it.
Edit, just found the documentation. It looks quite clear and well done.

Are you certain the cable is routed properly through the derailleur? Apex derailleurs have a little tab next to the pinch bolt and the cable must run OVER this tab, even though running the cable under the tab seems to make sense. Routing the cable under the tab will make the derailleur require excessive cable tension to make it move.

With hard shifting, your first step is always disconnect the cable. You want to determine if it's the cable, the derailleur, the shifter, or just some bad adjustment.
