SRAM Rival Front Derailleur Issues

Hey all,

I recently installed a SRAM Quarq (the S975, 53/39) on my Cervelo S2 w/ Rival. I previously had a 50/34 crank on it, but luckily my chain had enough slack to fit the new 53/39 (with a bit of B screw adjustment on the RD). However, I had to raise my FD to fit the 53/39, so I used the parktool guide for aligning and adjusting the FD, and I thought I did a pretty good job. However, it is almost impossible for me to shift from the 39 -> 53, unless I'm in my smallest rear cog. It almost seems like the gap between the inner and outer chainrings on the S975 is larger than on my old FSA Gossamer–could this be? Has anyone had experience with the Rival/S975 combo?

Thanks!

Don't have that combo. But when I was installing Rival on my Cross Check I ran into something similar. First make sure the cable is routed correctly on the FD. Second I had to allow a little more slack in the cable when it's in the small chainring. What was happening was as I shifted to the big chainring I would come up against the limit before the shifter clicked into the full shift position. It was locking in the trim position. A little more cable slack and I could make the shifter do a full shift.

Aha! You were almost completely correct: my H limiter screw was a bit too tight which was in fact stopping the cage too soon, so it wouldn't quite get all the way over. So I loosened it a bit, and voila, it work perfectly!

Thanks!
