    Ultegra ST-6703 Dual Controls (Problem?)

    Hello,

    I am new to this forum and I was wondering is somebody can help me with the
    following.

    I have just bought a new road bike, the Cube Agree Pro with the Ultegra
    group set. What I want to know is if the right shifter/brake control has
    a problem. When you try to shift up a gear with either controls, the cable
    is not pulled immediately, but the lever moves a bit to the inside and then
    force is needed in order to change gear. While the left control moves a
    little bit, the right has to move double the distance in order to engage and
    pull the cable.

    Does anybody know if this is normal ?
    Is there a way to shorten that distance?

    The dual controls are the Shimano Ultegra ST-6703.

    The reason I don't like that, is because when you ride and you are wearing
    gloves, the right brake sometimes slips because when I try to pull it, I am also
    pushing it towards the left. (and you can move it very easily until it engages
    the cable and finds resistance).

    I am including a photo in order to better show you what I mean.

    I hope somebody can shed some light on that.

    Thanks in advance!
    George.

    There is a bit of a learning curve to brifters. You need to get used to pulling straight back for braking. It does eventually get automatic. Whether there is actually a problem with the amount of movement before engaging or the amount of force required to shift would be best left up to the LBS where you purchased the bike.
