Thanks everybody for dragging me into 2010 when Dynasys became the cool thing. Somehow I managed to miss all of that, probably out riding my bike. It certainly is not mentioned in the adverts for shifters.
Let me take a step back and ask some advice: this is being driven by my wife's somewhat precarious balance, and her trouble in moving hands off the bar to shift. I am trying to keep the controls under her fingertips. We have tried bar-ends, Thumbies and stem-mounted levers, with little success. I see a choice between triggers and twist shifters, both of which look really out of place on the beautiful Betty Foy. But I have to go with the practical solution. If I go back to a 9-speed drivetrain I think I get more choices in shifters. Is that right? I am willing to scrap the whole 105 setup and start again with Riv-standard Deore if need be. This is attractive also because I had the bike spec'd and assembled by someone else, and he went with the 10-speed 11-28 cassette and 105 derailers. Turns out to have been a poor choice. Can anybody suggest a combination that's not quite so ugly? Or another solution for a wobbly rider?
