The 611 is built but essentially different, the seat is square and flat so that I can feel the barely falling edge of the saddle on the back of the thigh.
Here, the 612er is substantially "rounded" pulled down.
Who has the 611er problems should even try the 612. If more cushioned mat, made not so much pressure on the ischial tuberosity and is somewhat "round" shape.
4 stars not because me the saddle did not fit, but for the price policy. The 612 costs half, the cushioning has installed and "cushions" my feeling is the same as for the 611 active.
