    Tiagra FD Cabling Questions

    I'm fitting a Tiagra triple FD (4403) for the first time. On testing, the chain moves smoothly from small (30) to middle (42) chainring and then climbs reluctantly to the large (52) chainring. It goes down through the rings OK, but then the cable slackens and on the next test it only goes as far as the middle ring. Clearly there is something wrong with my cabling job, but I can't work out what it is. I need to go right back to the start again, so here are some basic questions that I would be very grateful if you could answer. Thanks.

    1] Should the cable be as vertical as possible between the cable stop and the fixing bolt?

    2] I assume the cable goes between the plate and the FD body, not between the bolt head and the plate. Am I right?

    3] Should the cable enter the fixing bolt in a clockwise direction (from inside to outside) or counter clockwise direction?

    4] The fixing bolt plate has a small 'tail' in one corner. Where should this end up - top, bottom, left, right?

    5] Should I pull the cable through the fixing bolt with significant strength, or just hand strength?

    6] Do I need to wrap the cable around the fixing bolt before tightening or just leave it vertical?

    7] How does the adjuster on the grip shifter affect things?

    1) No idea wtf that means
    2) Yes
    3) Should enter from the outside
    4) Cable should run on TOP of it then towards the anchor point (plate and FD body)
    5) You need to read the proper procedure on FD adjustment
    6) The cable does not need to be wrapped around
    7) Refer to link below

    Technical document on your FD + setup instructions. Alternatively there is also park tool which gives a general overview on how to set things up. A triple FD is one of the most finicky things to setup even when everything is compatible.

    Thank you kindly for your reply. Sorry about the obscurity of Q1. I have two cable stops that I can use. One is on the chainwheel side and brings the cable up directly underneath the fixing bolt - thus the cable is vertical. The other is on the non-chainwheel side and results in the cable meeting the fixing bolt at an angle. I was wondering if the positioning of the cable stop would affect the 'pull' in any way.

    Thanks again for your help.
