Ultegra Front Deraileur Chainring Size Compatability
I recently swapped my 52/42/30 Campy chainrings for to TA 46/40/30 chainrings to test out a crossover gearing setup. My front Deraileur is an Ultegra triple. I can't seem to shift into the largest chainring because the front Deraileur is sitting too high for the 46t ring. But if I lower it, then it won't clear the middle ring. Are front deraileurs designed for a specific size of chainrings? Are my chainring sizes not compatible? Help!
