I brought a short shifter from nottieboy for my 34. The shifter seems alright, but with some problems.
Problem 1: the end cap that came with it is larger than the original end cap and consequently does not fit in the selcter rod. I filed the new cap a bit and now it fits a little better.
Problem 2: the original end cap, when fitter to the new shifter does not much rotational play, due to the end of the short shifter not being a perfect sphere.
Problem 3: the supplied bush to raise the ball housing seems to be too big for the extended throw and the shifter slips out of the selecter rod. The throw between the end cap and the ball is longer by 10mm on the short shifter than the original however a 14mm bush was supplied. I am having a new bush made for $20 which will be ready for collection tomorrow.
I will let all know how it works out when fitted correctly.
