Here is what I have; Older Ultegra triple crank FC6503 (52-42-30) with a 45mm chainline per Shimano specs. I intended to use a new Ultegra double front derailer but it doesn't seem to have enough throw from low to high limit. I am using an older Sora Triple brifter and the front derailer will go from the 30 to 42 ring but it hits the high limit about half way between the 42 and 52 ring. I have adjusted the high limit to the maximum throw.
I ordered an Ultegra FD6603 triple and it seems to be doing the same. I know now the 6603 is for a 52-39-? crank set, but the derailer is hitting on the high limit, not the inner plate of the derailer against the middle chain ring.
What am I not seeing here?
Thanks and best regards,
