Everytime that I change to the big ring I have to do this stupid "half-shift", I would have no problem with this but it is so touchy that everytime I ATTEMPT to do this half shift, I down shift on accident. It is really frustrating to be ready to groove in the big ring and this happens. I have a 105 dr and a tiagra fr, as well as, tiagra shifters, does 105 or Ultegra have this problem? Is there anything that I can do to make it not as touchy now?
