Microshift makes a bar end shifter that is dynasys compatible. There are other options for thumb or downtube too.
Dynasys uses more cable pull distance for each shift, so the shifter and derailleur are different. As far as precision, it depends on how the friction is designed. You can get more cable pull distance by increasing lever travel or diameter. If a larger diameter, then precision would be about the same. A small diameter with more travel gives more tolerance between shifts. You can also make a 9 speed friction shifter work with dynasys by dremeling it to get more travel. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
