The M-D Line represents a maximum of relief. The M-D Line was developed for maximum relief of sensitive areas. Pressure distribution according to medical criteria. M-D provides maximum dip and, in combination with the high classic step shape, distributes the body weight to the sit bones. The 610 M-D active is suitable for the comfort-oriented mountain biker and the sporty trekking rider. The relief of the perineal area is very high at 82%. The 610 M-D active is equipped with the new active technology with a softer and lighter movement with less weight. The SQlab active saddle technology allows the saddle to follow the pedalling movement, which increases comfort, mobilises the intervertebral discs and minimises pressure on the sit bones. Pain in the lumbar region, especially on longer tours, can thus be reduced. The timeless design adapts perfectly to any bicycle.
