With the chain on the smallest chainring and largest cassette cog flip the small shift lever several times while pulling the cable out of the shifter. Confirm that the low limit screw is properly set. Pull all of the slack out of the cable while attaching the cable to the derailleur.
I checked that. but the cable end is seated properly in the shifter, and the shifter is down all the way. (made sure no more clicks were left).
I measured the amount of cable pull, it's pulling 3/8th inch. and it really needs to pull about 1/2 in to get the proper cage movement.
is the FD-6400 suppose to go with the brake/shifters? or are they only for downtube shifter?
I used to have a FD-6401, and it works fine. but had couldn't use it on the new frame cause of the seattube diameter mismatched the clamp. So bought this FD-6400 thinking it should be the same. but I suppose the difference is making itself known.
Will buy another FD-6401 to try, maybe it'll solve the problem.
Anyone have any ideas how much cable a brake/shifter suppose to pull and which FD match which shifter?
Thanks,
Thomas
