The M-D Line stands for maximum relief. It was developed to alleviate sensitive areas and ensures pressure distribution based on medical principles. M-D represents the maximized dip, which, in combination with the high classic step shape, distributes body weight onto the sit bones. The 610 M-D active is suitable for comfort-oriented mountain bikers and sport-oriented trekking riders. The relief in the perineal area is 82%. The 610 M-D active is equipped with the new active technology, which allows for softer and lighter movement with less weight. Thanks to the SQlab active saddle technology, the saddle follows the pedaling motion, increasing comfort, mobilizing the intervertebral discs, and minimizing pressure on the sit bones. This can help reduce lower back pain, especially on longer rides. The timeless design adapts optimally to any bike.
