The 604 Active has the same construction as the top of the range 602 active. Just the padding is kept a little softer. This makes the 604 ideal for both medium length and short rides on the trekking and city bike. The design is plain and black so it will aesthetically suit any bike. The high quality cover material has already proven itself on the new Ergowave® models. This provides the 604 active with an exceptional value for money.
A perfect pressure distribution from a medical perspective is ensured through use of SQlab’s tried and proven step saddle profile. The sensitive soft tissue areas are equally relieved for both men and women. Thanks to SQlab's active saddle technology, the saddle can follow the pedalling motion and the degree of movement can be adjusted to the rider’s weight. This slight movement allows the spinal discs to be mobilised while also reducing the pressure to the sit bones.
The raised tail provides more support at the back, resulting in a more efficient power transfer.
Comfortable riding position
The undulating shape of the ERGOLUX® stretching from the stern to the front corresponds perfectly to the mostly bulbous ramus of the ischium. The enlarged, less selective contact surface, provides for a best possible pressure distribution within the ramus of the ischium.
Lower saddle nose
The lower saddle nose relieves the pressure on sensitive areas of both men and women alike.
SQlab active system comfort
The SQlab active technology enables lateral movement of the pelvis of up to 7 °, which, from a biomechanical viewpoint is similar to running. This increases pedal efficiency and, above all, comfort. At the same time, the intervertebral discs are relieved and mobilized. The lateral movement can be adapted to the rider's weight via the Comfortsticks
