Just got a (used) bike with st-rs685 shifters (hydraulic brakes, 2x11 mechanical shifting). The behavior of the front shifter is strange, I am trying to understand whether my shifter is defective or not.
Per shimano, I understand that these front shifters have a total of 4 FD positions. From outboard to inboard, these are: high, high trim, low, low trim (this is the innermost position).
When the chain on the big ring, a complete sweep of the small lever triggers 1 or 2 clicks (from the high trim and high positions respectively) and leaves the FD positioned in the 'low' position. To move the FD into the low trim position (all the way inboard) requires two sweeps of the small lever. Its not possible to go from the big ring to the innermost position in one lever movement.
Is this as designed?
