Seen many different opinions if Simplex retrofriction will or will not work with normal (Campagnolo) DT shifter bosses. Will they. I have attached a pic of the type of shifters I am talking about. They do not have this curved "washer" that comes with shimano shifters hence I am not sure if they work and if they work right out of the box or if I have to do some modificaitons to get them to work.
Thankfull for any hints
