I have a "funny" problem on the Roubaix, I wonder if anyone has some suggestions.

Issue is the FD sometimes takes some time to drop from big ring to little ring. It invariably is well into a ride, it NEVER happens in the first hour on the road. But an hour or two into a ride, it will sometimes take a few seconds or even several seconds to finally drop onto the small ring. I checked the cable and pivot points, all are nice and smooth/lubed. In the stand, it shifts up/down crisply. Even if I put it in the big ring at night, next morning it will drop onto the small ring without delay.

Any ideas???
