I got a st 4700 tiagra shifter and fd r7000 front derailleur in double crankset. My problem is when i am in the big ring and try to trim down i pull the little lever on the shifter and hear a good click, feel the movememt in the cable but the front derailleur does not move? There is good amount of cable tension i checked. And also trim on the small ring works. Can this be a cable routing issue or is this normal?
UPDATE :I installed the tiagra fd-4700 derailleur and the trim works fine. Actually the 105 fd r7000 derailleur is not fully compatible with Tiagra shifters.
