The active movement can be regulated via the new switch function, in two settings. M-D line More relief - less pressure. The M-D Line was developed for maximum relief of sensitive areas and allows pressure to be distributed according to medical criteria. M-D stands for maximized dip and, in combination with the high classic step shape, distributes the body weight onto the sit bones. This shape in combination with the CrMo rails make the M-D Line suitable for heavy riders. If for you the comfort on the sit bones is more important than the relief of the perineal area, we recommend the ERGOLUX® series.
