Sram Rival zero-loss & trim issues
Hi All,
I've got a Sram Rival group on my bike, 2009 shifters, which I believe is the year Sram introduced zero-loss to the Rival shifters.
Anyways, if I adjust the front shifting so that there is no initial slack when shifting from the small to large chainring, I lose my trim setting in the large chainring. The shifter will still click, as if releasing enough cable for the trim setting, but the front derailleur doesn't move.
Alternatively, I can loosen the front shift cable enough that I have some initial play when shifting to the large chainring, but this allows me to use my trim position again.
Anyone have any suggestions or ideas on what I might be doing wrong in terms of setting up my drivetrain?

Is it harder to complete a shift into the big ring? Maybe you're hitting the high limit screw around the trim location and loading up the cable so when you release it again you've only decompressed the housings and stuff.

This. When I first set up my rival group I made this mistake. With a little tweaking it works just fine.
