FD won't shift
I bought a used bike and didn't notice on my test ride that the cranks (not OEM) are not centered. Upon inspection, it appeared that the seller had put both 2.5mm spacers on the left side. I moved one spacer over to the drive side as per the crankset's instructions, but then the clamp-on Ultegra FD-6800 wouldn't shift into the big ring even with the limit screws backed off completely and the cable tightened until it barely grazes the inner chainring. What are my options?
FWIW it's an FSA Gossamer Pro Modular AGX+ crankset on a 2016 Diamondback Haanjo Trail.
